Container

Specify a container image to build or pull from a remote registry. You may also optionally specify services to deploy, tasks or tests to run inside the container.
Note that the runtime services have somewhat limited features in this module type. For example, you cannot specify replicas for redundancy, and various platform-specific options are not included. For those, look at other module types like helm or kubernetes.
Below is the schema reference. For an introduction to configuring Garden modules, please look at our Configuration guide. The reference is divided into two sections. The first section lists and describes the available schema keys. The second section contains the complete YAML schema.

include
Specify a list of POSIX-style paths or globs that should be regarded as the source files for this module. Files that do not match these paths or globs are excluded when computing the version of the module, as well as when responding to filesystem watch events.
Note that you can also exclude files by placing .gardenignore files in your source tree, which use the same format as .gitignore files.
Also note that specifying an empty list here means no sources should be included.
