`CONTAINER1`\n\n ```\n docker run -d -t --name CONTAINER1 ubuntu top\n bd78d93154cff5e8b40d19b1676670a49f582d2522384ecfe0d9e7d60846891e\n ```\n\n 1. start `docker-sshd`\n\n ```\n docker-sshd\n ```\n\n 1. connect to container with ssh\n\n ```\n ssh CONTAINER1@127.0.0.1 -p 2232\n root@bd78d93154cf:/#\n ```\n\n## Options\n\n```\n--address value, -l value listening address (default: \"0.0.0.0\")\n--port value, -p value listening port (default: 2232)\n--server-key value, -i value server key files, support wildcard (default: \"/etc/ssh/ssh_host_ed25519_key\")\n--command value, -c value default exec command (default: \"/bin/sh\")\n```\n\n### Docker related Environment\n\n * `DOCKER_HOST to` set the URL to the docker server, default unix:///var/run/docker.sock.\n * `DOCKER_API_VERSION` to set the version of the API to use, leave empty for latest.\n * `DOCKER_CERT_PATH` to specify the directory from which to load the TLS certificates (ca.pem, cert.pem, key.pem).\n * `DOCKER_TLS_VERIFY` to enable or disable TLS verification (off by default).\n\nsee \u003chttps://pkg.go.dev/github.com/docker/docker/client#FromEnv\u003e for more detail\n\n## Connecting from vscode\n\nMake sure your container meet the [prerequisites](https://code.visualstudio.com/docs/remote/linux#_remote-host-container-wsl-linux-prerequisites).\nAdditionally, install [nc](https://linux.die.net/man/1/nc) to your container to have tcp redirect
