Configuration
Monitor just needs a bit of information in order to build your image.
Repo configuration
To specify the github repo to build, just give it the name of the repo and the branch under repo config. The name is given like mbecker20/monitor, it includes the username / organization that owns the repo.
Many repos are private, in this case a Github access token is needed by the building server.
It can either come from and account defined in the core configuration,
or in the periphery configuration of the building server.
These are specified in the config like username = "access_token".
Docker build configuration
In order to docker build, monitor just needs to know the build directory and the path of the Dockerfile relative to the repo, you can configure these in the build config section.
If the build directory is the root of the repository, you pass the build path as .. If the build directory is some folder of the repo, just pass the name of the the folder. Do not pass the preceding "/". for example build/directory
The dockerfile's path is given relative to the build directory. So if your build directory is build/directory and the dockerfile is in build/directory/Dockerfile.example, you give the dockerfile path simply as Dockerfile.example.
Image registry
Monitor supports pushing to DockerHub and Github Container Registry (ghcr.io). Any of the Docker / Github accounts that are specified in config, between the core config and builder, will be available to use. Additionally, allowed organizations for both DockerHub and Github can be specified on the core config and attached to builds. Doing so will cause the images to be published under the organization's namespace rather than the account's.
When connecting a build to a deployments, the default behavior is for the deployment to inherit the registry configuration from the build. In cases where that account isn't available to the deployment, another account can be chosen in the deployment config.
:::note
In order to publish to the Github Container Registry, your Github access token must be given the write:packages permission.
See the Github docs here.

Adding build args
The Dockerfile may make use of build args. Build args can be passed using the gui by navigating to the Build Args tab in the config. They are passed in the menu just like in the would in a .env file:
BUILD_ARG1=some_value
BUILD_ARG2=some_other_value
Note that these values are visible in the final image using docker history, so shouldn't be used to pass build time secrets. Use secret mounts for this instead.
