Spin off another container on host machine from an existing container

I am currently using Docker Desktop for Mac.

My requirement is to spin off a container from another container.

Situation:

Container A has a service running which upon request looks for a swarm manager and spin off another container B. I have started single node swarm manager on my machine. I can not use host network_mode because docker for MAC exposes light weight linux vm as host and not my actual localhost. I have tried this also : https://forums.docker.com/t/access-host-not-vm-from-inside-container/11747/7

Any possible solution?

The idea is that your container can access your host. So, use the Engine API provided by Docker:

POST /containers/create

You will have to post json that contains the details of the new container.

Engine API v1.24

The daemon listens on unix:///var/run/docker.sock but you can Bind Docker to another host/port or a Unix socket.

You can listen on port 2375 on all network interfaces with -H tcp://0.0.0.0:2375, or on a particular network interface using its IP address: -H tcp://192.168.59.103:2375. It is conventional to use port 2375 for un-encrypted, and port 2376 for encrypted communication with the daemon.
