ssh_tunnel/README.md

An ansible role to set up an ssh tunnel and port forwardings from the remote machine to local machines

Required variables

... e.g. in group_vars

• ssh_tunnel_pubkey: The complete line to be used in authorized_keys, e.g. "ssh-ed25519 AAAA[...]aU root@mylocalmachine"
• ssh_tunnel_privkey: The content of the corresponding private key file, including the BEGIN and END tags. It is highly recommended to put this inside an encrypted ansible vault.
• tunneled_ports: A list of port forwardings. Example:

  tunneled_ports:
  - exposed_port: 80 # public port at the remote machine
    ephemeral_port: 10080 # internal port at remote machine's localhost address. The ssh tunnel will fetch traffic from there
    dest_host: my-internal-http-server.local.domain.tld # domain or IP address of the destination machine. Must be reachable form the local machine.
    dest_port: 80 # open port at the destination machine
    protocols: ["tcp"] # list of protocols for this forwarding. "tcp" and "udp" are supported.
