In Progress

IP Tables script:

• https://github.com/hyperledger/indy-node-container/blob/main/run/set_iptables.sh
• Scripts including DDOS protection already merged. Improvements under ways:
  • https://github.com/hyperledger/indy-node-container/issues/102
    • Add to README: flush Chain (default docker) before running the script
  • https://github.com/hyperledger/indy-node-container/pull/113

Indy Node Controller

• Current problem: Podman dependency removed since `apt-get install -y podman` requires `dbus-user-session` which then requires `systemd`
  • Podman is used (at least by IFIS)!
  • actually we only need podman cli → better package?
  • other base image?
  • https://github.com/hyperledger/indy-node-container/issues/112
  • @Cristian Kubis
• The Upgrade Prozess in Indy needs to be improved in order to propperly support upgrading containers
  • Discuss https://github.com/hyperledger/indy-node-container/issues/108 
    • Problem: No explizit IPs in default run setting
• The principal Controller solution mounting the host docker socket into the controller container might be re-discussed as well

Tagging of Container releases

• Include indy node version
• For upgrade!
• Release less flavours

Container

• Use smaller base images
• python-slim + pypi indy packages?
  • Phillipp: Caution: pypi packages are not identical to deb versions
  • differences regarding config files for indy-node (https://github.com/hyperledger/indy-node/blob/ubuntu-20.04-upgrade/build-scripts/ubuntu-2004/prepare-package.sh)

Stale

Issues

• https://github.com/hyperledger/indy-node-container/issues/96
  • probably resolved?
• Maintainers.md: https://github.com/hyperledger/indy-node-container/issues/98
  • https://github.com/hyperledger/indy-node-container/pull/109

Network connectivity test script

Idea: Script to test that IP Tables rules are as they should be

• At least check that node can connect (TCP lvl) to all other nodes
• Bonus: Check that connection from outside is not possible

Still 2do

Load Test Script by Christian Bormann

• on hold

Alerting

• Sebastian Z finished work on slack alerting action.
• Send webhook to Sebastian Schmittner → Forward to Stephen Curranto add to github repo, then MR github action
• Replace scan → github security alerts or do both?
  • BOTH
  • Sebastian Schmittner

Logging

• Stale PR https://github.com/hyperledger/indy-node-container/pull/83

• Discussion today:
  • Rather document how to edit the https://github.com/hyperledger/indy-node-container/blob/main/run/etc_indy/indy_config.py then overwriting those variables at container start through init script
  • Network Name → same!?
  • Definietly keep READE + docker logging explanation
  • → sesinsible default for logging in docker compose
  • Sebastian Schmittner

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
