Use container as a build agent in Azure Devops
when running builds on hosted agents sometimes it lacks little things, sometimes big things. Also, to ensure consistency between development, test and production, its better to use the same container. What I was doing previously:
- docker pull
- docker run xxx
And there is nothing wrong with this, except you need to mount your code to the container and you have to do all the commands in one go or issue several near identical docker run commands which is suboptimal. Turns out Azure Devops can run your pipeline inside the container on the hosted agent, which is really neat. Additionally, all your tasks will run in the root of the repo and all your build variables will be available inside container as is. So you dont need to mount the repo inside container and you dont need to declare variables for the docker run command.
