Docker and Azure Containers

Azure Container

Creating a container instance in Azure follows the basic steps of building an image, creating a container and pushing to registry from Docker Container. The easier way is to push a container directly from VSCode to an Azure Container Registry. Otherwise you can create a Container Instance from a Azure Container Registry container in the Azure Portal, but make sure the right port is opened. Underneath is a GitHub workflow which can automatically create, build and push an image to a container registry on commit.

Docker

When you've created a project you wish to to run as a container, you can dot his in a few simple steps. Firstly you must create a dockerfile, to let docker know what it must do with you project. Most IDE's have this function built in. Secondly you run this command:

docker build -t {LOGINSERVER}/{PROJECTNAME}:TAG .

This creates a image for your container. From here there are many option to create a container and push it to the right location. In VSCode you're able to use the Docker extension, but alternatively you're able to manually push with this command:

docker push {LOGINSERVER}/{PROJECTNAME}:TAG

If you've done all of this successfully your container is now at the right location.
