Setup Travis CI Enterprise 2.x

Travis CI Enterprise works with your GitHub.com or GitHub Enterprise (Enterprise Server below version 3.4) setup. Please also note the Travis CI Enterprise 2.x is EOL, so we are strongly recommending an upgrade to Travis CI Enterprise 3.x.

Prerequisites #

• A valid Travis CI Enterprise license or trial license. If you’re interested in using High Availability, please let us know so we can get your trial license configured.

• At least two virtual machines on your private cloud that meet the system requirements

• The secret and clientid of a GitHub.com or GitHub Enterprise OAuth application configured with:

  • Homepage URL - https://<your-travis-ci-enterprise-domain>
  • Authorization callback URL - https://<your-travis-ci-enterprise-domain>/api + URLs must include https or http at the beginning and cannot have trailing slashes.

System Requirements #

The standard setup consists of the Travis CI Enterprise Platform which hosts the web UI and related services, and one or more Worker hosts which run the tests/jobs in isolated containers using LXC and Docker.

Each dedicated host or hypervisor (VMWare, OpenStack using KVM, or EC2) should run Ubuntu 16.04, ideally using Linux 3.16, and have at least 16 gigs of RAM and 8 CPUs.

If you’re running on EC2, we recommend the c4.2xlarge instance type for both Platform and Worker. We also recommend using an image that uses EBS for the root volume, as well as allocating 40 gigs of space to it.

For high availability (HA) configurations, you will also need:

• Redis,
• RabbitMQ
• Postgres

You can also try services like compose.com, if you would like these services hosted outside your organization.

Setup Enterprise Platform virtual machine #

The Travis CI Enterprise Platform handles licensing, coordinates worker processes, and maintains the Enterprise user and admin dashboard. It must be installed on its own machine instance, separate from that of the Travis CI Enterprise worker. We recommend using AWS’ c4.2xlarge instance running Ubuntu 16.04 LTS or later as the underlying operating system.

1. On your virtual machine management platform, create a Travis CI Platform Security Group.

   If you’re setting up your AMI for the first time, you need to create a Security Group. From the EC2 management console, create an entry for each port in the table below:

   Port	Service	Description
   8800	Custom TCP Rule	This port is to access the admin dashboard for your Enterprise installation.
   5672	Custom TCP Rule	For RabbitMQ Non-SSL.
   4567	Custom TCP Rule	For RabbitMQ SSL.
   443	HTTPS	Web application over HTTPS access.
   80	HTTP	Web application access.
   22	SSH	SSH access.

2. If you’re using a hostname and not just an IP address, this would be a time to configure it.

3. On your new virtual machine, download and run the installation script:

    curl -sSL -o /tmp/installer.sh https://enterprise.travis-ci.com/install
    sudo bash /tmp/installer.sh
   

4. In your browser, navigate to https://<your-travis-ci-enterprise-domain>:8800 (your Enterprise installation’s hostname, port 8800) to complete the setup:

   1. Add a secure certificate or configure a trusted one.
   2. Upload your Travis CI Enterprise license.
   3. Configure access to the Admin Console with a password or using OpenLDAP. This controls access to the Admin Console, not the Travis CI Enterprise instance.
   4. Connect your GitHub Enterprise or GitHub.com with Travis CI enterprise.
   5. Optionally, configure Email, Metrics and Caches.
   6. Copy the RabbitMQ password for the Worker setup.

Additional configuration steps may be required if you have decided to use a self-signed certificate. For more information, please see our page on SSL Certificate Management.

Setup the Enterprise Worker virtual machine #

The Travis CI Enterprise Worker manages build containers, and reports build statuses to the platform. It must be installed on a separate machine instance from the Platform. We recommend using instances running Ubuntu 16.04 LTS or later as the underlying operating system.

Make sure you have already set up the Enterprise Platform and have the RabbitMQ password and the hostname from the Platform Dashboard.

After that, follow instructions to set up a Worker.

Running builds #

Skip over to the Onboarding Guide and connect some repositories to your new Travis CI Setup!

Contact Enterprise Support #

To get in touch with us, please write a message to enterprise@travis-ci.com. If possible, please include as much of the following as you can:

• Description of the problem - what are you observing?
• Which steps did you try already?
• A support bundle (see table below on how to obtain it)
• Log files from all workers (They can be found at /var/log/upstart/travis-worker.log - please include as many as you can retrieve).
• If a build failed or errored, a text file of the build log

Since the announcement in Q3 2020, the most up to date version of Travis CI Enterprise is 3.x line. There are not any new releases for version 2.2 and the support patches has been limited since March 2021 as well. For existing users of Travis CI 2.x we strongly recommend upgrading to the latest Travis CI Enterprise 3.x.

Have you made any customizations to your setup? While we may be able to see some information (such as hostname, IaaS provider, and license expiration), there are many other things we cannot see which could lead to something not working. Therefore, we would like to ask you to also answer the questions below in your support request (if applicable):

• How many machines are you using / what is your Kubernetes cluster setup?
• Do you use configuration management tools (Chef, Puppet)?
• Which other services do interface with Travis CI Enterprise?
• Which Version Control system (VCS) do you use together with Travis CI Enterprise (e.g. github.com, GitHub Enterprise, or BitBucket Cloud)?
• If you are using GitHub Enterprise, which version of it?

We are looking forward to helping!
