Conduit

Experimental deployment system for Docker.

Conduit exposes an endpoint that receives webhooks (i.e. from Docker Hub). Upon receiving the hook, Conduit will pull the new image, deploy a new container from the updated image and then remove the original container.

Usage

Docker.

docker run
    -d
    --name conduit
    -p 8080:8080
    -v /var/run/docker.sock:/var/run/docker.sock
    ehazlett/conduit -r <repo-name> -t <token>

Where <repo-name> is a Docker repository name such as ehazlett/go-demo and <token> is a custom token string. The -r arg can be specified multiple times.

Example:

docker run
    -d
    --name conduit
    -p 8080:8080
    -v /var/run/docker.sock:/var/run/docker.sock
    ehazlett/conduit -r ehazlett/go-demo -t s3cr3+

Then add a webhook url to http://<your-conduit-host>:<your-conduit-port>?token=<token>

You can also specify a list of tags for deploy. Conduit will only deploy and rotate containers that are using that tag. For example, if you have containers with both v1 and v2 tags running, if you specify v2 as a tag in Conduit, it will only deploy the v2 containers when receiving a webhook.

Testing

To simulate a webhook using curl:

curl -d '{"repository": {"repo_name": "namespace/reponame"}}' http://<docker-host-ip>:8080?token=yourtoken
