Docker is a containerisation system, Docker Compose is a way to define how multiple Docker containers interact. And you can do it without creating a new dab (Distribution Application Bundle) file, but just using familiar and well-known docker-compose. Following Docker Swarm services are extremely useful in externalizing the configuration: Docker Secrets (available in Docker 1. Docker Compose. The changes include a separate top level key named volumes. This is the setup I ended up using. Plugins can be installed in a separate directory and mounted using Docker or Kubernetes, however make sure you build plugins with native dependencies using the same base image as the Verdaccio Dockerfile. This guide uses an example to show how the Storidge volume plugin is called within a Docker Compose file. In the development stage, the application files came from bind mounts set up with docker-compose, so it made sense to specify the command in the docker-compose. Docker volumes on Windows are always created in the path of the graph driver, which is where Docker stores all image layers, writeable container layers and volumes.
