Ignores SSH_STRICT_HOST_IP_CHECK=false

[Megamannen]

This still checks the hosts

My compose:

version: '3.7'

services:
  tunnel:
    image: jnovack/autossh
    container_name: tunnel
    environment:
      - SSH_REMOTE_USER=pi
      - SSH_REMOTE_HOST=docker.lan
      - SSH_REMOTE_PORT=22
      - SSH_TUNNEL_PORT=2222
      - SSH_TARGET_HOST=192.168.88.254
      - SSH_TARGET_PORT=22
      - SSH_STRICT_HOST_IP_CHECK=false
    restart: unless-stopped
    volumes:
      - ./id_rsa:/id_rsa
      - ./known_hosts:/known_hosts

output when running:

As you can see -o StrictHostKeyChecking=yes

Ok, no shell master. But don't you compare "false" (string) to false (boolean) here?

if [ "${SSH_STRICT_HOST_IP_CHECK}" = false ]; then
