Images for self-hosted DevOps agents running in Docker. The preparation of these images has been described in this post: Self-hosted Azure DevOps agents running in Docker.
Most of the bash scripts in this repository are adopted from the official Hosted images prepared by Microsoft, with minor modifications, taken from this repository: https://github.com/microsoft/azure-pipelines-image-generation/.
The images in this repository feature a modified start.sh script that supports caching of tools and agent files across restarts, as described in the blog post linked above.
You can use the provided build.sh file to create images on your host.
Otherwise, first create the base image:
# from Ubuntu 18.04-base:
docker build -t devopsagentubuntu:18.04 .
Then create other images that depend on it.
It is possible to create an agent with several tools, by editing the FROM statement as desired, in the provided Dockerfiles. For example, it is possible to compose an agent with Python, .NET Core, and PowerShell Core by first building the python image on top of the base image; then building the dotnet image on top of the python image.
This technique can be used in build pipelines, to compose an agent with all desired tools.
Create an access token in Azure DevOps, then:
docker run -e AZP_URL=<YOUR-ORGANIZATION-URL> \
-e AZP_TOKEN=<YOUR-TOKEN> \
-e AZP_AGENT_NAME='Self-hosted Ubuntu 18.04' devopsubuntu18.04:latest
# or, from inside the container, in /azp:
AZP_URL=<YOUR-ORGANIZATION-URL> \
AZP_TOKEN=<YOUR-TOKEN> \
AZP_AGENT_NAME='Self-hosted Ubuntu 18.04' ./start.sh
