no issue - When stopping `yarn dev` with ctrl+c in the dev container, you'd get an error because the container doens't have `ps` installed, which is used by node under the hood. Adding this dependency fixed the error so `yarn dev` (and other commands) exit cleanly |

Dev Container Setup
devcontainer.json
This file contains the configuration for the dev container. It is used to define the setup of the container, including things like port bindings, environment variables, and other dev container specific features.
It points to a docker compose file in the .devcontainer/.docker directory, which in turn relies on a Dockerfile in the same directory.
Dockerfile
The Dockerfile in this directory uses a multi-stage build to allow for multiple types of builds without duplicating code and ensuring maximum consistency. The following targets are available:
base: The bare minimum base image used to build and run Ghost. Includes the operating system, node, and some build dependencies, but does not include any Ghost code or dependencies.base-devcontainer: everything frombase, plus additional development dependencies like the stripe-cli and playwright. No code or node dependencies.full-devcontainer: everything frombase-devcontainer, plus Ghost's code and all node dependenciesdevelopment: an alternative tofull-devcontainerintended for manual development e.g. with docker compose. Add Ghost's code and installs dependencies with some optimizations for the yarn cache
Docker Compose
Similarly, the docker compose configuration relies on merging compose files to create the final configuration. The base.compose.yml file contains the bare minimum configuration, and can be extended by specifying additional services or modifying the existing ones by supplying additional compose files. For example, to run the development.compose.yml file, you would use the following command:
docker compose -f .devcontainer/docker/base.compose.yml -f .devcontainer/docker/development.compose.yml up
There is an alias yarn compose script in the top level package.json which points to the appropriate compose.yml files for local development.
This setup gives us the flexibility to create multiple different docker compose configurations, while ensuring a base level of consistency across configurations.
