+Using the default configuration, this installation method has a number of limitations:
-This is a package-based installation method. Start with the @provision.sh@ script which is available by cloning the @{{ branchname }}@ branch from "https://git.arvados.org/arvados.git":https://git.arvados.org/arvados.git . The @provision.sh@ script and its supporting files can be found in the "arvados/tools/salt-install":https://git.arvados.org/arvados.git/tree/refs/heads/{{ branchname }}:/tools/salt-install directory in the Arvados git repository.
+* all services run on the same machine, and they will compete for resources. This includes any compute jobs.
+* it uses the local machine disk for Keep storage (under the @/tmp@ directory). There may not be a lot of space available.
+* it installs the @crunch-dispatch-local@ dispatcher, which can run just eight concurrent CWL jobs. These jobs will be executed on the same machine that runs all the Arvados services and may well starve them of resources.
-This procedure will install all the main Arvados components to get you up and running in a single host. The whole installation procedure takes somewhere between 15 to 60 minutes, depending on the host resources and its network bandwidth. As a reference, on a virtual machine with 1 core and 1 GB RAM, it takes ~25 minutes to do the initial install.
+It is possible to start with the single host installation method and modify the Arvados configuration file later to address these limitations. E.g. switch to a "different storage volume setup":{{site.baseurl}}/install/configure-s3-object-storage.html for Keep, and switch to "the cloud dispatcher":{{site.baseurl}}/install/crunch2-cloud/install-dispatch-cloud.html to provision compute resources dynamically.
-The @provision.sh@ script will help you deploy Arvados by preparing your environment to be able to run the installer, then running it. The actual installer is located at "arvados-formula":https://git.arvados.org/arvados-formula.git/tree/refs/heads/{{ branchname }} and will be cloned during the running of the @provision.sh@ script. The installer is built using "Saltstack":https://saltproject.io/ and @provision.sh@ performs the install using master-less mode.
+h2(#prerequisites). Prerequisites
-After setting up a few variables in a config file (next step), you'll be ready to run it and get Arvados deployed.
+* git
+* a dedicated (virtual) machine for your Arvados server with at least 2 cores and 8 GiB of RAM, running a "supported Arvados distribution":{{site.baseurl}}/install/install-manual-prerequisites.html#supportedlinux
+* a DNS hostname that resolves to the IP address of your Arvados server
+* ports 443, 8800-8805 need to be reachable from your client (configurable in @local.params@, see below)
+* port 80 needs to be reachable from everywhere on the internet (only when using "Let's Encrypt":#lets-encrypt)
+* an SSL certificate matching the hostname in use (only when using "bring your own certificate":#bring-your-own)
-h2(#choose_configuration). Choose the desired configuration
+h2(#download). Download the installer
-For documentation's sake, we will use the cluster name <i>arva2</i> and the domain <i>arv.local</i>. If you don't change them as required in the next steps, installation won't proceed.
+{% include 'download_installer' %}
-Arvados' single host installation can be done in two fashions:
+h2(#copy_config). Copy the configuration files
-* Using a single hostname, assigning <i>a different port (other than 443) for each user-facing service</i>: This choice is easier to setup, but the user will need to know the port/s for the different services she wants to connect to.
-* Using multiple hostnames on the same IP: this setup involves a few extra steps but each service will have a meaningful hostname so it will make easier to access them later.
-
-Once you decide which of these choices you prefer, copy one the two example configuration files and directory, and edit them to suit your needs.

+h2(#further_customization). Further customization of the installation (modifying the salt pillars and states)
If you want or need further customization, you can edit the Saltstack pillars and states files. Pay particular attention to the <i>pillars/arvados.sls</i> one. Any extra <i>state</i> file you add under <i>local_config_dir/states</i> will be added to the salt run and applied to the host.

-h2(#final_steps). Final configuration steps
-
-Once the deployment went OK, you'll need to perform a few extra steps in your local browser/host to access the cluster.
-
-h3(#ca_root_certificate). Install the CA root certificate (required in both alternatives)
-
-Arvados uses SSL to encrypt communications. Its UI uses AJAX which will silently fail if the certificate is not valid or signed by an unknown Certification Authority.
-
-For this reason, the @arvados-formula@ has a helper state to create a root certificate to authorize Arvados services. The @provision.sh@ script will leave a copy of the generated CA's certificate (@arvados-snakeoil-ca.pem@) in the script's directory so you can add it to your workstation.
-
-Installing the root certificate into your web browser will prevent security errors when accessing Arvados services with your web browser.
-
-# Go to the certificate manager in your browser.
-#* In Chrome, this can be found under "Settings → Advanced → Manage Certificates" or by entering @chrome://settings/certificates@ in the URL bar.
-#* In Firefox, this can be found under "Preferences → Privacy & Security" or entering @about:preferences#privacy@ in the URL bar and then choosing "View Certificates...".
-# Select the "Authorities" tab, then press the "Import" button. Choose @arvados-snakeoil-ca.pem@
-
-The certificate will be added under the "Arvados Formula".
-
-To access your Arvados instance using command line clients (such as arv-get and arv-put) without security errors, install the certificate into the OS certificate storage.

-h3(#single_host_multiple_hostnames_dns_configuration). DNS configuration (single host / multiple hostnames)
-
-When using multiple hostnames, after the setup is done, you need to set up your DNS to be able to access the cluster.
-
-If you don't have access to the domain's DNS to add the required entries, the simplest way to do it is to edit your @/etc/hosts@ file (as root):
-
-<notextile>
-<pre><code>export CLUSTER="arva2"
-export DOMAIN="arv.local"
-export HOST_IP="127.0.0.2" # This is valid either if installing in your computer directly
- # or in a Vagrant VM. If you're installing it on a remote host
- # just change the IP to match that of the host.
-echo "${HOST_IP} api keep keep0 collections download ws workbench workbench2 ${CLUSTER}.${DOMAIN} api.${CLUSTER}.${DOMAIN} keep.${CLUSTER}.${DOMAIN} keep0.${CLUSTER}.${DOMAIN} collections.${CLUSTER}.${DOMAIN} download.${CLUSTER}.${DOMAIN} ws.${CLUSTER}.${DOMAIN} workbench.${CLUSTER}.${DOMAIN} workbench2.${CLUSTER}.${DOMAIN}" >> /etc/hosts

-At this point you should be able to log into the Arvados cluster. The initial URL will be:
-
-* https://workbench.arva2.arv.local
