Usage

cassian forward
Opens tunnels for all ports defined in cassian.yaml. Stays alive until you press ctrl+c. The instance keeps running after you disconnect.

​
Configuration

Ports are defined in cassian.yaml: 
ports:
  - "8000:8000"     # local:container
  - "8888:8888"
  - "8080:3000"     # local 8080, container 3000

​
Example

# Start a server in the container
cassian exec -d "python -m http.server 8000"

# Forward it locally
cassian forward

# In another terminal
curl http://localhost:8000

​

Notes

  • Ports also forward automatically during cassian ssh
  • If a local port is already in use, that tunnel is skipped with a warning
