This demonstrates the usage of https://github.com/apocas/dockerode to remotely deploy docker containers. Feel free to add a comment or send a PR if you want more examples.

Get the image

• You may clone the git repo and build the image using the Dockerfile

$ docker build -t mgireesh05/launcher .

• Alternatively, you may pull the image from docker registry

$ docker pull mgireesh05/launcher

Run the image

$ docker run -p 8000:8000 -v /var/run/docker.sock:/var/run/docker.sock mgireesh05/launcher

APIs

• /launch_containers

E.g. This API will

• pull node:0-slim container
• start three instances and expose port 80 of each to 8001, 8002, and 8003 on the host
• mounts /tmp/mount on host to /mount in the container

POST http://localhost:8000/launch_containers
