Create a lightweight Alpine Linux based SSH tunnel to a host. Uses pure SSH, no fluff.
For single TCP port applications (database/webserver/debugging access) a SSH tunnel is far faster and simpler than using a *** like Open***; see this excellent blog post for more info.
For example I use it to create a SSH tunnel from a GCP Kubernetes cluster into an on prem bastion host in order to talk to an on prem MySQL database; it SSHs onto the internal LAN and connects me to the internal on prem MySQL server.
Inspired by https://github.com/iadknet/docker-ssh-client-light and GCP CloudSQL Proxy
bash# local port on your machine/k8s cluster LOCAL_PORT=3306 # remote port from the machine your SSHing into REMOTE_PORT=3306 # OPTIONAL defaults to 127.0.0.1 REMOTE_SERVER_IP="my.internal.mariadb.server" # the bastion/host you're connecting to SSH_BASTION_HOST="bastion.host" # OPTIONAL defaults to 22 SSH_PORT=2297 SSH_USER="tunnel_user"
Also be sure to inject/mount your private ssh key into the container to /ssh_key/id_rsa
bash# connect to our mongo server in AWS via a bastion host # now we can use a connection string like this: # mongodb://localhost:27017 # to talk to our AWS mongo install docker run -it --rm \ -p 27017:27017 \ -e LOCAL_PORT=27017 \ -e REMOTE_PORT=27017 \ -e SSH_BASTION_HOST=34.135.248.162 \ -e REMOTE_SERVER_IP=aws-nlb-mongo-fake.internal-us-east-1.es.amazonaws.com \ -e SSH_USER=ec2-user \ -v ~/.ssh/id_rsa:/ssh_key/id_rsa:ro \ jujhars13/docker-ssh-tunnel # connection established, now we can mongo away locally mongo --host localhost --port 27017
