Sandbox using DockerΒΆ

This is a good way to test The Bastion within seconds, but read the FAQ if you're serious about using containerization in production.

The sandbox image is available for the following architectures: linux/386, linux/amd64, linux/arm/v6, linux/arm/v7, linux/arm64, linux/ppc64le, linux/s390x.

  • Let's run the docker image:
docker run -d -p 22 --name bastiontest ovhcom/the-bastion:sandbox
  • Or, if you prefer building the docker image yourself, you can: use the two commands below. Of course, if you already typed the docker run command above, you can skip the following commands:
docker build -f docker/Dockerfile.debian10 -t bastion:debian10 .
docker run -d -p 22 --name bastiontest bastion:debian10
  • Configure the first administrator account (get your public SSH key ready)
docker exec -it bastiontest /opt/bastion/bin/admin/ poweruser auto
  • We're now up and running with the default configuration! Let's setup a handy bastion alias, and test the info command:
PORT=$(docker port bastiontest | cut -d: -f2)
alias bastion="ssh poweruser@ -tp $PORT -- "
bastion --osh info
  • It should greet you as being a bastion admin, which means you have access to all commands. Let's enter interactive mode:
bastion -i
  • This is useful to call several --osh plugins in a row. Now we can ask for help to see all plugins:
$> help
  • If you have a remote machine you want to try to connect to through the bastion, fetch your egress key:
$> selfListEgressKeys
  • Copy this public key to the remote machine's authorized_keys under the .ssh/ folder of the account you want to connect to, then:
$> selfAddPersonalAccess --host <remote_host> --user <remote_account_name> --port-any
$> ssh <remote_account_name>@<remote_host>
  • Note that you can connect directly without using interactive mode, with:
bastion <remote_account_name>@<remote_machine_host_or_ip>

That's it! You can head over to the USAGE section on the left menu for more information. Be sure to check the help of the bastion with bastion --help, along with the help of each osh plugin with bastion --osh command --help.

Also don't forget to customize your bastion.conf file, which can be found in /etc/bastion/bastion.conf (for Linux).
