Compose2ContainerApps

This is a proof of concept to take Docker Compose files (following the spec) and converting them to YAML files that can be used to deploy Azure ContainerApps services.

Work To Be Done

There are lots of things that the Compose file can express that are not supported. We should add some warnings about those configuration elements that are not going to be represented - things like volume mounts, network configurations, etc..

Things to figure out:

• A compose file can describe multiple containers and their connections. ContainerApps has two options, multiple containers on the same host (basically a k8s pod) or separate ContainerApps in the same environment with an HTTP ingress between them. Currently, it creates separate ContainerApps deployments for each service defined.
• A compose file can expose multiple ports or ranges (internal ingress) or define multiple ports or ranges (external ingress). ContainerApps exposes one port either internally or externally (exclusive) per ContainerApp.
• Something else?

Building The App

This app should build with minimal dependencies. It's been tested with Rust 1.57.

cargo build

Running The App

The application has four mandatory parameters and two optional ones (that have default values).

Converts Docker Compose files to Azure ContainerApps yaml configuration files

USAGE:
    compose2containerapp.exe --containerapps-environment-id <kubeEnvironmentId> --location <location> --name <name> --resource-group <resourceGroup> [ARGS]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -i, --containerapps-environment-id <kubeEnvironmentId>    Resource ID for the ContainerApps environment.
    -l, --location <location>                                 Resource group location for the ContainerApps environment.
    -n, --name <name>                                         Resource Name for the ContainerApps revision.
    -g, --resource-group <resourceGroup>                      Resource Group for the ContainerApps environment.

ARGS:
    <INPUT>     Path to read the Docker Compose yaml configuration file. [default: ./docker-compose.yml]
    <OUTPUT>    Base file name to write the Azure ContainerApps yaml configuration files.  Output file name will be
                prefixed with the service name. [default: containerapps.yml]
