In Progress

🎉 Upstream Contribution

We have contributed our repo to Hyperledger: https://github.com/hyperledger/indy-node-container

HL Teams: https://github.com/orgs/hyperledger/teams/indy-node-container-maintainers

• Adapt Readme https://github.com/hyperledger/indy-node-container/pull/80
  • run/READM -> links
  • container refs (run) -> hyperledger
  • https://github.com/hyperledger/indy-node-container/blob/main/.github/workflows/trivy-all.yml
    • tryvy ref -> HL (owner like in other action)
• Minutes
  • Move to HL Confluence
  • @Echsecutor -> ask ??? for Confluence Space

Release automation / Scans

• https://github.com/hyperledger/indy-node-container/issues/46
• Add Slack bot
  • https://action-slack.netlify.app/usage was added to ID Union Slack
• Sebastian Zickau continues in a personal fork

Logging

Suggestion by Marquart:

• limit docker logs
  • https://docs.docker.com/config/containers/logging/configure/

logging:
      driver: "json-file"
      options:
        max-file: "5"
        max-size: "100m"

• default log level?

  • https://github.com/hyperledger/indy-node-container/blob/main/run/etc_indy/indy_config.py
  • set to 1
  • += run/README.md

• mounting log files (/var/log/indy)

  • https://github.com/hyperledger/indy-node-container/blob/main/run/docker-compose.yml
  • rotation? ⚠️
  • += run/README

• Also limit container journal -> Docker build? or Startup script?

  • Read man pages for journalctl ! 😉
  • Default roataion?

# /var/log/journal
sudo journalctl --rotate
sudo journalctl --vacuum-size=100M
sudo journalctl --vacuum-files=5 

Stale

Fixing current images write consensus

• Ubuntu 20 / node 1.13.0~dev206 eventually runs into consensus problems
  • do not use 1.13.0~dev206 for Debian images (for now)!
  • Todo: rather produce Debioan images similar to https://github.com/IDunion/indy-node-container/blob/main/build/Dockerfile.ubuntu18
  • @Echsecutor

Contribution to Node 1.13.0 / Ubuntu 20.04 Release

• Concretely: Need Ubuntu 20.04 systemd container
  • https://github.com/hyperledger/indy-test-automation/blob/main/system_node_only/docker/node/Dockerfile.ubuntu-2004
  • Hyperledger Indy has a Test Automation Suite which starts the Indy software as a systemd service in a container to simulate operation in a VM. Mainly it is about Pool Restart, Upgrade, Start & Stop Node
  • Could probably be based on https://github.com/solita/docker-systemd/tree/master (which is not maintained anymore)
  • other examples
    • requires sysbox-runc: https://github.com/nestybox/dockerfiles/blob/master/ubuntu-focal-systemd/Dockerfile
    • requires privileged mode: https://github.com/fauust/docker-systemd
    • requires privileged mode: https://github.com/robertdebock/docker-ubuntu-systemd

See https://github.com/hyperledger/indy-test-automation/blob/main/system_node_only/docker_setup.py#L78

Update from @Robin today: Looks promising!

Metrics

• Carlos: https://github.com/IDunion/indy-node-monitor
• https://github.com/WadeBarnes/indy-node-monitor/tree/monitoring-stack
• Existing Prometheus + Grafana setup by IFIS

Security

The node keys handling is currently sub optimal (env variable). Should be improved to e.g. file based setup: https://github.com/IDunion/indy-node-container/issues/52

• Cristian already has a nice setup elsewhere and offers to port it
  • https://github.com/internet-sicherheit/sovrin-container
  • Merge of IFIS repo?

Indy-Test-Automation

• Issue#102: Indy Node system tests depend on the Sovrin package
  • Improve our own testing!

Support for non-docker setup

• Helm Charts
  • Might geht interesting at some point in the future 😉
    • Potential Clients Spherity/MGM
• Podman
  • https://github.com/IDunion/indy-node-container/issues/48

Next Meeting

• Weekly Fri 9:15-10:00 (UTC+1)
