34 h2(#introduction). Introduction
36 This multi host installer is the recommendend way to set up a production Arvados cluster. These instructions include specific details for installing on Amazon Web Services (AWS), which are marked as "AWS specific". However with additional customization the installer can be used as a template for deployment on other cloud provider or HPC systems.
38 h2(#prerequisites). Prerequisites and planning
40 h3. Cluster ID and base domain
42 Choose a 5-character cluster identifier that will represent the cluster. Here are "guidelines on choosing a cluster identifier":../architecture/federation.html#cluster_id . Only lowercase letters and digits 0-9 are allowed. Examples will use @xarv1@ or @${CLUSTER}@, you should substitute the cluster id you have selected.
44 Determine the base domain for the cluster. This will be referred to as @${DOMAIN}@.
46 For example, if CLUSTER is @xarv1@ and DOMAIN is @example.com@, then @controller.${CLUSTER}.${DOMAIN}@ means @controller.xarv1.example.com@.
48 h3(#DNS). DNS hostnames for each service
50 You will need a DNS entry for each service. When using the "Terraform script":#terraform to set up your infrastructure, these domains will be created automatically using AWS Route 53.
52 In the default configuration these are:
54 # @controller.${CLUSTER}.${DOMAIN}@
55 # @ws.${CLUSTER}.${DOMAIN}@
56 # @keep0.${CLUSTER}.${DOMAIN}@
57 # @keep1.${CLUSTER}.${DOMAIN}@
58 # @keep.${CLUSTER}.${DOMAIN}@
59 # @download.${CLUSTER}.${DOMAIN}@
60 # @*.collections.${CLUSTER}.${DOMAIN}@ -- important note, this must be a wildcard DNS, resolving to the @keepweb@ service
61 # @workbench.${CLUSTER}.${DOMAIN}@
62 # @workbench2.${CLUSTER}.${DOMAIN}@
63 # @webshell.${CLUSTER}.${DOMAIN}@
64 # @shell.${CLUSTER}.${DOMAIN}@
66 For more information, see "DNS entries and TLS certificates":install-manual-prerequisites.html#dnstls.
68 h3. Install Terraform and AWS CLI (AWS specific)
70 If you are going to use Terraform to set up the infrastructure on AWS, you will need to install the "Terraform CLI":https://developer.hashicorp.com/terraform/tutorials/aws-get-started/install-cli tool installed on your computer, as well as the "AWS CLI":https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html tool.
72 h2(#download). Download the installer
74 {% assign local_params_src = 'multiple_hosts' %}
75 {% assign config_examples_src = 'multi_host/aws terraform/aws'%}
76 {% include 'download_installer' %}
78 h2(#setup-infra). Set up your infrastructure
80 h3(#terraform). Create AWS infrastructure with Terraform (AWS specific)
82 We provide a set of Terraform code files that you can run to create the necessary infrastructure on Amazon Web Services.
84 These files are located in the @arvados/tools/salt-install/terraform/aws/@ directory and are divided in three sections:
86 # The @vpc/@ subdirectory controls the network related infrastructure of your cluster, including firewall rules and split-horizon DNS resolution.
87 # The @data-storage/@ subdirectory controls the stateful part of your cluster, currently only sets up the S3 bucket for holding the Keep blocks and in the future it'll also manage the database service.
88 # The @services/@ subdirectory controls the hosts that will run the different services on your cluster, makes sure that they have the required software for the installer to do its job.
90 h4. Software requirements & considerations
92 {% include 'notebox_begin' %}
93 The Terraform state files (that keep crucial infrastructure information from the cloud) will be saved inside each subdirectory, under the @terraform.tfstate@ name. These will be committed to the git repository used to coordinate deployment. It is very important to keep this git repository secure, only sysadmins that will be responsible for maintaining your Arvados cluster should have access to it.
94 {% include 'notebox_end' %}
96 h4. Terraform code configuration
98 Each section described above contain a @terraform.tfvars@ file with some configuration values that you should set before applying each configuration. You should set the cluster prefix and domain name in @vpc/terraform.tfvars@:
100 <pre><code>region_name = "us-east-1"
101 # cluster_name = "xarv1"
102 # domain_name = "example.com"</code></pre>
104 If you don't set the variables @vpc/terraform.tfvars@ file, you will be asked to re-enter these parameters every time you run Terraform.
106 The @data-storage/terraform.tfvars@ and @services/terraform.tfvars@ let you configure the location of your ssh public key (default @~/.ssh/id_rsa.pub@) and the instance type to use (default @m5a.large@).
108 h4. Create the infrastructure
110 Build the infrastructure by running @./installer.sh terraform@. The last stage @services/@ will output the information needed to set up the cluster's domain and continue with the installer. for example:
112 <pre><code>$ ./installer.sh terraform
114 Apply complete! Resources: 16 added, 0 changed, 0 destroyed.
118 arvados_sg_id = "sg-02f999a99973999d7"
119 cluster_name = "xarv1"
120 deploy_user = "admin"
121 domain_name = "example.com"
122 letsencrypt_iam_access_key_id = "AKAA43MAAAWAKAADAASD"
123 letsencrypt_iam_secret_access_key = <sensitive>
125 "controller" = "10.1.1.1"
128 "keepproxy" = "10.1.1.2"
130 "workbench" = "10.1.1.5"
133 "controller" = "18.235.116.23"
134 "keep0" = "34.202.85.86"
135 "keep1" = "38.22.123.98"
136 "keepproxy" = "34.231.9.201"
137 "shell" = "44.208.155.240"
138 "workbench" = "52.204.134.136"
140 route53_dns_ns = tolist([
141 "ns-1119.awsdns-11.org",
142 "ns-1812.awsdns-34.co.uk",
143 "ns-437.awsdns-54.com",
144 "ns-809.awsdns-37.net",
146 subnet_id = "subnet-072a999f939989710"
147 vpc_cidr = "10.1.0.0/16"
148 vpc_id = "vpc-0999994998399923a"
152 h4. Additional DNS configuration
154 Once Terraform has completed, the infrastructure for your Arvados cluster is up and running. You are almost ready to have the installer connect to the instances to install and configure the software.
156 The domain names for your cluster (e.g.: controller.xarv1.example.com) are managed via "Route 53":https://aws.amazon.com/route53/ and the TLS certificates will be issued using "Let's Encrypt":https://letsencrypt.org/ .
158 You will need to configure the parent domain to delegate to the newly created zone. In other words, you need to configure @${DOMAIN}@ (e.g. "example.com") to delegate the subdomain @${CLUSTER}.${DOMAIN}@ (e.g. "xarv1.example.com") to the nameservers that contain the Arvados hostname records created by Terraform. You do this by creating an @NS@ record on the parent domain that refers to the appropriate name servers. These are the domain name servers listed in the Terraform output parameter @route53_dns_ns@.
160 If your parent domain is also controlled by Route 53, the process will be like this:
162 # Log in to the AWS Console and navigate to the service page for *Route 53*
163 # Go to the list of *Hosted zones* and click on the zone for the parent domain
164 # Click on *Create record*
165 # For *Record name* put the cluster id
166 # For *Record type* choose @NS - Name servers for a hosted zone@
167 # For *Value* add the values from Terraform output parameter @route53_dns_ns@, one hostname per line, with punctuation (quotes and commas) removed.
168 # Click *Create records*
170 h4. Other important output parameters
172 Take note of @letsencrypt_iam_access_key_id@ and @letsencrypt_iam_secret_access_key@ for setting up @LE_AWS_*@ variables in @local.params@. The certificates will be requested when you run the installer.
174 You'll see that the @letsencrypt_iam_secret_access_key@ data is obscured; to retrieve it you'll need to run the following command inside the @services/@ subdirectory:
176 <pre><code>$ terraform output letsencrypt_iam_secret_access_key
177 "FQ3+3lxxOxxUu+Nw+qx3xixxxExxxV9jFC+XxxRl"</code></pre>
179 You'll also need @subnet_id@ and @arvados_sg_id@ to set up @DriverParameters.SubnetID@ and @DriverParameters.SecurityGroupIDs@ in @local_config_dir/pillars/arvados.sls@ for when you "create a compute image":#create_a_compute_image.
181 h3(#inframanual). Create required infrastructure manually
183 If you will be setting up infrastructure without using the provided Terraform script, here are the recommendations you will need to consider.
185 h4. Virtual Private Cloud (AWS specific)
187 We recommend setting Arvados up in its own "Virtual Private Cloud (VPC)":https://docs.aws.amazon.com/vpc/latest/userguide/what-is-amazon-vpc.html
189 When you do so, you need to configure a couple of additional things:
191 # "Create a subnet for the compute nodes":https://docs.aws.amazon.com/vpc/latest/userguide/configure-subnets.html
192 # You should set up a "security group which allows SSH access (port 22)":https://docs.aws.amazon.com/vpc/latest/userguide/VPC_SecurityGroups.html
193 # Make sure to add a "VPC S3 endpoint":https://docs.aws.amazon.com/vpc/latest/privatelink/vpc-endpoints-s3.html
195 h4(#keep-bucket). S3 Bucket (AWS specific)
197 We recommend "creating an S3 bucket":https://docs.aws.amazon.com/AmazonS3/latest/userguide/Welcome.html for data storage named @${CLUSTER}-nyw5e-000000000000000-volume@. We recommend creating an IAM role called @${CLUSTER}-keepstore-00-iam-role@ with a "policy that can read, write, list and delete objects in the bucket":configure-s3-object-storage.html#IAM . With the example cluster id @xarv1@ the bucket would be called @xarv1-nyw5e-000000000000000-volume@ and the role would be called @xarv1-keepstore-00-iam-role@.
199 These names are recommended because they are default names used in the configuration template. If you use different names, you will need to edit the configuration template later.
201 h4(#hosts). Required hosts
203 You will need to allocate several hosts (physical or virtual machines) for the fixed infrastructure of the Arvados cluster. These machines should have at least 2 cores and 8 GiB of RAM, running a supported Linux distribution.
205 {% include 'supportedlinux' %}
207 Allocate the following hosts as appropriate for your site. On AWS you may choose to do it manually with the AWS console, or using a DevOps tool such as CloudFormation or Terraform. With the exception of "keep0" and "keep1", all of these hosts should have external (public) IP addresses if you intend for them to be accessible outside of the private network or VPC.
209 The installer will set up the Arvados services on your machines. Here is the default assignment of services to machines:
213 ## arvados api server
214 ## arvados controller (recommendend hostname @controller.${CLUSTER}.${DOMAIN}@)
215 ## arvados websocket (recommendend hostname @ws.${CLUSTER}.${DOMAIN}@)
216 ## arvados cloud dispatcher
217 ## arvados keepbalance
218 # KEEPSTORE nodes (at least 2)
219 ## arvados keepstore (recommendend hostnames @keep0.${CLUSTER}.${DOMAIN}@ and @keep1.${CLUSTER}.${DOMAIN}@)
221 ## arvados keepproxy (recommendend hostname @keep.${CLUSTER}.${DOMAIN}@)
222 ## arvados keepweb (recommendend hostname @download.${CLUSTER}.${DOMAIN}@ and @*.collections.${CLUSTER}.${DOMAIN}@)
224 ## arvados workbench (recommendend hostname @workbench.${CLUSTER}.${DOMAIN}@)
225 ## arvados workbench2 (recommendend hostname @workbench2.${CLUSTER}.${DOMAIN}@)
226 ## arvados webshell (recommendend hostname @webshell.${CLUSTER}.${DOMAIN}@)
227 # SHELL node (optional)
228 ## arvados shell (recommended hostname @shell.${CLUSTER}.${DOMAIN}@)
230 When using the database installed by Arvados (and not an "external database":#ext-database), the database is stored under @/var/lib/postgresql@. Arvados logs are also kept in @/var/log@ and @/var/www/arvados-api/shared/log@. Accordingly, you should ensure that the disk partition containing @/var@ has adequate storage for your planned usage. We suggest starting with 50GiB of free space on the database host.
232 h4. Additional prerequisites when preparing machines to run the installer
234 # From the account where you are performing the install, passwordless @ssh@ to each machine
235 This means the client's public key should added to @~/.ssh/authorized_keys@ on each node.
236 # Passwordless @sudo@ access on the account on each machine you will @ssh@ in to
237 This usually means adding the account to the @sudo@ group and having a rule like this in @/etc/sudoers.d/arvados_passwordless@ that allows members of group @sudo@ to execute any command without entering a password.
238 <pre>%sudo ALL=(ALL:ALL) NOPASSWD:ALL</pre>
239 # @git@ installed on each machine
240 # Port 443 reachable by clients
242 (AWS specific) The machine that runs the arvados cloud dispatcher will need an "IAM role that allows it to manage EC2 instances.":{{site.baseurl}}/install/crunch2-cloud/install-dispatch-cloud.html#IAM
244 If your infrastructure differs from the setup proposed above (ie, different hostnames), you can still use the installer, but "additional customization may be necessary":#further_customization .
246 h2(#localparams). Edit @local.params@
248 This can be found wherever you choose to initialize the install files (@~/setup-arvados-xarv1@ in these examples).
250 # Set @CLUSTER@ to the 5-character cluster identifier (e.g "xarv1")
251 # Set @DOMAIN@ to the base DNS domain of the environment, e.g. "example.com"
252 # Edit Internal IP settings. Since services share hosts, some hosts are the same. See "note about /etc/hosts":#etchosts
253 # Edit @CLUSTER_INT_CIDR@, this should be the CIDR of the private network that Arvados is running on, e.g. the VPC.
254 CIDR stands for "Classless Inter-Domain Routing" and describes which portion of the IP address that refers to the network. For example 192.168.3.0/24 means that the first 24 bits are the network (192.168.3) and the last 8 bits are a specific host on that network.
255 _AWS Specific: Go to the AWS console and into the VPC service, there is a column in this table view of the VPCs that gives the CIDR for the VPC (IPv4 CIDR)._
256 # Set @INITIAL_USER_EMAIL@ to your email address, as you will be the first admin user of the system.
257 # Set each @KEY@ / @TOKEN@ / @PASSWORD@ to a random string. You can use @installer.sh generate-tokens@
258 <pre><code>$ ./installer.sh generate-tokens
259 BLOB_SIGNING_KEY=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
260 MANAGEMENT_TOKEN=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
261 SYSTEM_ROOT_TOKEN=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
262 ANONYMOUS_USER_TOKEN=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
263 WORKBENCH_SECRET_KEY=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
264 DATABASE_PASSWORD=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
265 # Set @DATABASE_PASSWORD@ to a random string (unless you "already have a database":#ext-database then you should set it to that database's password)
266 Important! If this contains any non-alphanumeric characters, in particular ampersand ('&'), it is necessary to add backslash quoting.
267 For example, if the password is @Lq&MZ<V']d?j@
268 With backslash quoting the special characters it should appear like this in local.params:
269 <pre><code>DATABASE_PASSWORD="Lq\&MZ\<V\'\]d\?j"</code></pre>
271 h3(#etchosts). Note on @/etc/hosts@
273 Because Arvados services are typically accessed by external clients, they are likely to have both a public IP address and a internal IP address.
275 On cloud providers such as AWS, sending internal traffic to a service's public IP address can incur egress costs and throttling. Thus it is very important for internal traffic to stay on the internal network. The installer implements this by updating @/etc/hosts@ on each node to associate each service's hostname with the internal IP address, so that when Arvados services communicate with one another, they always use the internal network address. This is NOT a substitute for DNS, you still need to set up DNS names for all of the services that have public IP addresses (it does, however, avoid a complex "split-horizon" DNS configuration).
277 It is important to be aware of this because if you mistype the IP address for any of the @*_INT_IP@ variables, hosts may unexpectedly fail to be able to communicate with one another. If this happens, check and edit as necessary the file @/etc/hosts@ on the host that is failing to make an outgoing connection.
279 h2(#keep). Configure Keep storage
281 The @multi_host/aws@ template uses S3 for storage. Arvados also supports "filesystem storage":configure-fs-storage.html and "Azure blob storage":configure-azure-blob-storage.html . Keep storage configuration can be found in in the @arvados.cluster.Volumes@ section of @local_config_dir/pillars/arvados.sls@.
283 h3. Object storage in S3 (AWS Specific)
285 Open @local_config_dir/pillars/arvados.sls@ and edit as follows:
287 # In the @arvados.cluster.Volumes.DriverParameters@ section, set @Region@ to the appropriate AWS region (e.g. 'us-east-1')
289 If you did not "follow the recommendend naming scheme":#keep-bucket for either the bucket or role, you'll need to update these parameters as well:
291 # Set @Bucket@ to the value of "keepstore bucket you created earlier":#keep-bucket
292 # Set @IAMRole@ to "keepstore role you created earlier":#keep-bucket
294 {% include 'ssl_config_multi' %}
296 h2(#authentication). Configure your authentication provider (optional, recommended)
298 By default, the installer will use the "Test" provider, which is a list of usernames and cleartext passwords stored in the Arvados config file. *This is low security configuration and you are strongly advised to configure one of the other "supported authentication methods":setup-login.html* .
300 h2(#ext-database). Using an external database (optional)
302 The standard behavior of the installer is to install and configure PostgreSQL for use by Arvados. You can optionally configure it to use a separately managed database instead.
304 Arvados requires a database that is compatible with PostgreSQL 9.5 or later. For example, Arvados is known to work with Amazon Aurora (note: even idle, Arvados services will periodically poll the database, so we strongly advise using "provisioned" mode).
306 # In @local.params@, remove 'database' from the list of roles assigned to the controller node:
308 [controller.${CLUSTER}.${DOMAIN}]=api,controller,websocket,dispatcher,keepbalance
312 # In @local.params@, set @DATABASE_INT_IP@ to the database endpoint (can be a hostname, does not have to be an IP address).
313 <pre><code>DATABASE_INT_IP=...
315 # In @local.params@, set @DATABASE_PASSWORD@ to the correct value. "See the previous section describing correct quoting":#localparams
316 # In @local_config_dir/pillars/arvados.sls@ you may need to adjust the database name and user. This can be found in the section @arvados.cluster.database@.
318 h2(#further_customization). Further customization of the installation (optional)
320 If you are installing on AWS and have followed all of the naming conventions recommend in this guide, you probably don't need to do any further customization.
322 If you are installing on a different cloud provider or on HPC, other changes may require editing the Saltstack pillars and states files found in @local_config_dir@. In particular, @local_config_dir/pillars/arvados.sls@ contains the template (in the @arvados.cluster@ section) used to produce the Arvados configuration file that is distributed to all the nodes. Consult the "Configuration reference":config.html for a comprehensive list of configuration keys.
324 Any extra Salt "state" files you add under @local_config_dir/states@ will be added to the Salt run and applied to the hosts.
326 h2(#create_a_compute_image). Create a compute image
328 {% include 'branchname' %}
330 On cloud installations, containers are dispatched in Docker daemons running in the _compute instances_, which need some additional setup. If you will use a HPC scheduler such as SLURM you can skip this section.
332 *Start by following "the instructions to build a cloud compute node image":{{site.baseurl}}/install/crunch2-cloud/install-compute-node.html using the "compute image builder script":https://github.com/arvados/arvados/tree/{{ branchname }}/tools/compute-images* .
334 Once you have that image created, Open @local_config_dir/pillars/arvados.sls@ and edit as follows (AWS specific settings described here, other cloud providers will have similar settings in their respective configuration section):
336 # In the @arvados.cluster.Containers.CloudVMs@ section:
337 ## Set @ImageID@ to the AMI produced by Packer
338 ## Set @DriverParameters.Region@ to the appropriate AWS region
339 ## Set @DriverParameters.AdminUsername@ to the admin user account on the image
340 ## Set the @DriverParameters.SecurityGroupIDs@ list to the VPC security group which you set up to allow SSH connections to these nodes
341 ## Set @DriverParameters.SubnetID@ to the value of SubnetId of your VPC
342 # Update @arvados.cluster.Containers.DispatchPrivateKey@ and paste the contents of the @~/.ssh/id_dispatcher@ file you generated in an earlier step.
343 # Update @arvados.cluster.InstanceTypes@ as necessary. The example instance types are for AWS, other cloud providers will of course have different instance types with different names and specifications.
344 (AWS specific) If m5/c5 node types are not available, replace them with m4/c4. You'll need to double check the values for Price and IncludedScratch/AddedScratch for each type that is changed.
346 h2(#installation). Begin installation
348 At this point, you are ready to run the installer script in deploy mode that will conduct all of the Arvados installation.
350 Run this in the @~/arvados-setup-xarv1@ directory:
353 ./installer.sh deploy
356 This will install and configure Arvados on all the nodes. It will take a while and produce a lot of logging. If it runs into an error, it will stop.
358 h2(#test-install). Confirm the cluster is working
360 When everything has finished, you can run the diagnostics.
362 Depending on where you are running the installer, you need to provide @-internal-client@ or @-external-client@.
364 If you are running the diagnostics from one of the Arvados machines inside the private network, you want @-internal-client@ .
366 You are an "external client" if you running the diagnostics from your workstation outside of the private network.
369 ./installer.sh diagnostics (-internal-client|-external-client)
372 h3(#debugging). Debugging issues
374 The installer records log files for each deployment.
376 Most service logs go to @/var/log/syslog@.
378 The logs for Rails API server and for Workbench can be found in
380 @/var/www/arvados-api/current/log/production.log@
382 @/var/www/arvados-workbench/current/log/production.log@
384 on the appropriate instances.
386 Workbench 2 is a client-side Javascript application. If you are having trouble loading Workbench 2, check the browser's developer console (this can be found in "Tools → Developer Tools").
388 h3(#iterating). Iterating on config changes
390 You can iterate on the config and maintain the cluster by making changes to @local.params@ and @local_config_dir@ and running @installer.sh deploy@ again.
392 If you are debugging a configuration issue on a specific node, you can speed up the cycle a bit by deploying just one node:
395 ./installer.sh deploy keep0.xarv1.example.com@
398 However, once you have a final configuration, you should run a full deploy to ensure that the configuration has been synchronized on all the nodes.
400 h3(#common-problems). Common problems and solutions
402 h4. PG::UndefinedTable: ERROR: relation \"api_clients\" does not exist
404 The arvados-api-server package sets up the database as a post-install script. If the database host or password wasn't set correctly (or quoted correctly) at the time that package is installed, it won't be able to set up the database.
406 This will manifest as an error like this:
409 #<ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: relation \"api_clients\" does not exist
412 If this happens, you need to
414 1. correct the database information
415 2. run @./installer.sh deploy xarv1.example.com@ to update the configuration on the API/controller node
416 3. Log in to the API/controller server node, then run this command to re-run the post-install script, which will set up the database:
417 <pre>dpkg-reconfigure arvados-api-server</pre>
418 4. Re-run @./installer.sh deploy@ again to synchronize everything, and so that the install steps that need to contact the API server are run successfully.
420 h4. Missing ENA support (AWS Specific)
422 If the AMI wasn't built with ENA (extended networking) support and the instance type requires it, it'll fail to start. You'll see an error in syslog on the node that runs @arvados-dispatch-cloud@. The solution is to build a new AMI with --aws-ena-support true
424 h2(#initial_user). Initial user and login
426 At this point you should be able to log into the Arvados cluster. The initial URL will be
428 https://workbench.@${CLUSTER}.${DOMAIN}@
430 If you did *not* "configure a different authentication provider":#authentication you will be using the "Test" provider, and the provision script creates an initial user for testing purposes. This user is configured as administrator of the newly created cluster. It uses the values of @INITIAL_USER@ and @INITIAL_USER_PASSWORD@ the @local.params@ file.
432 If you *did* configure a different authentication provider, the first user to log in will automatically be given Arvados admin privileges.
434 h2(#post_install). After the installation
436 As part of the operation of @installer.sh@, it automatically creates a @git@ repository with your configuration templates. You should retain this repository but be aware that it contains sensitive information (passwords and tokens used by the Arvados services).
438 As described in "Iterating on config changes":#iterating you may use @installer.sh deploy@ to re-run the Salt to deploy configuration changes and upgrades. However, be aware that the configuration templates created for you by @installer.sh@ are a snapshot which are not automatically kept up to date.
