If you are familiar with Docker, you probably have also heard about Podman. Podman doesn’t try to do many things that Docker does, it’s a daemonless tool that provides an easy way to run, find and build OCI containers. We are happy to include documentation on how to run Webhook Relay tunnelling agent with Podman and also to announce that we are now providing agent images that are built on top of Redhat’s Universal Base Image (UBI).

Getting started

First, get a token key & secret pair from Once you got it, to launch a container via Podman we will be using our ubi8 based image webhookrelay/webhookrelayd-ubi8:latest.

Podman has very similar run syntax to Docker’s so you will probably feel right at home if you have used Docker before:

podman run -it

You can find “podman run” command docs here. From that page let’s look at environment variable configuration as we will need to supply access token and secret:

podman run -d --env RELAY_KEY=your-token-key --env RELAY_SECRET=your-token-secret --env BUCKETS=your-bucket-name --network host webhookrelay/webhookrelayd-ubi8

Here we also added:

Now, we can check whether the container is running:

podman ps
<container ID> About a minute ago Up About a minute ago gallant_bardeen

To view container logs:

podman logs <container ID>
2020-05-31 21:26:43.267 INFO using standard transport...
2020-05-31 21:26:43.356 INFO webhook relay ready... {"host": "", "buckets": ["podman-test"]}

That’s it, to remove container once you are done:

podman rm <container ID> -f
