Docker in GitHub Actions

Tibor Kiss Automation, Containers, Docker, Git, Technical Thursday Docker, Github

I am sure you know the automation actions in GitHub. Official definition by GitHub:

Automate, customize, and execute your software development workflows right in your repository with GitHub Actions.
help.github.com

GitHub Actions are small tasks which help you to create customized workflows. With them you can step up to the highest level of development automation.

You can find several useful actions on GitHub Marketplace which support your efforts toward to better automation.

Additionally 2 days ago Docker announced that they had released their first GitHub Action. You can find some details here.

As you can see the example is simple and easy to follow regarding their approach. Obviously, this is not enough to achieve your goals quickly so I would like to provide some useful links where you will find the related information for a good start:

If you have a cool suggestion regarding GitHub Action please share with us.

Have a well automated day. 🙂

Observastions and tips

Tibor Kiss Containers, Docker Containers, Docker, Windows, Windows Containers 0

Here you can find some observations about Docker on Windows.

Observatons and tips about Docker on Windows
After you start a container with the -a switch “docker start -a <container name>” then you want to use “docker exec -it <container name> powershell” although it is enter the container it is frozen. Without -a everithing is fine.
When you create a container pelase rename it with this command: Rename-Computer -NewName $oNewContainerName . Then please restart the docker container. If you miss this your container won’t start any more after a Docker host restart.
Configuration file in Windows: “C:\ProgramData\Docker\Containers\<GUID of container>\config.json” és “C:\ProgramData\Docker\Containers\<GUID of container>\hostconfig.json“
Please make a copy from the configuration files. That could be usefull when yor container does not want to start adfter a Docker host restart. When you meet this message: “Win32 API call returned error r1=2147942452 err=You were not connected because a duplicate name exists on the network. If joining a domain, go to System in Control Panel to change the computer name and try again.” you merely need to overwrite the config files from backup then your container will start correctly. Other workaround to fix your containers: Open config.json to edit Find and delete the next section: “Error”:”<Error message>”, Save config.json Start your docker container
Windows Feature installation. When you want to install/add/enable a new feature in Windows it required the installation media. Especially the SXS dorectory from installation media. In this case the usage of our powershell command: Add-WindowsFeature <comma separated feature list> -Source “<Path of installation media>\sources\sxs”
The DEL does not work in Docker console. You must use Backspace instead of DEL.

Feel free to get in touch with any comment, feedback or questions.
