Seldon Core Operator OCI Image

This repository is intended as a demonstration of how to port an OCI image that it otherwise defined using a Dockerfile to one built with rockcraft.

It provides a direct port of this Dockerfile.

Critically, this image includes pebble to start and manage the Seldon Core operator.

Build steps

# Install some deps
$ sudo snap install rockcraft --classic --edge
$ sudo snap install skopeo --edge --devmode

# Pack the ROCK (optionally add --verbose)
$ rockcraft pack

# For the following commands, you must either use `sudo` or ensure your user is a member of the
# `docker` group, or the commands will fail.

# Import the ROCK into the local docker image cache
$ sudo skopeo --insecure-policy copy oci-archive:seldon-core-operator_1.14.1_amd64.rock docker-daemon:jnsgruk/seldon-core-operator:1.14.1

# Run the image, invoking `manager` through pebble
$ docker run --rm -it jnsgruk/seldon-core-operator:1.14.1

TODO

  • Validate if the YAML resources in /tmp/operator-resources are required
  • Test with an actual charm deployment
  • Fine-tune the default Pebble layer
  • Run the operator as a non-root user
  • Trim the default image size using chiselled ubuntu
