[maelvls]

Preview: https://deploy-preview-1612--cert-manager.netlify.app/announcements/2024/12/10/contribfest-kubecon-eu-2025/

As discussed in https://kubernetes.slack.com/archives/CDEQJ0Q8M/p1733224974283799?thread_ts=1733224600.818759&cid=CDEQJ0Q8M, Richard and I want to submit something to ContribFest at KubeCon EU 2025. The ContribFest will take place on April 2nd, 2024. Feel free to add your name to the list of maintainers if you want to take part.

/hold until the submission gets approved.

For context, here is the list of the previous ContribFest sessions that took place in Salt Lake a month ago: https://kccncna2024.sched.com/overview/type/%F0%9F%9A%A8+Contribfest

CFP Title:

🚨 ContribFest: Dive Into cert-manager and Start Contributing!

CFP Abstract:

Join us for a hands-on, interactive session with the cert-manager maintainers and community! cert-manager, a graduated CNCF project, automates certificate management for Kubernetes and is a critical component for securing cloud-native applications. This workshop is perfect for both first-time contributors and seasoned open-source enthusiasts. You'll learn about cert-manager's architecture, the role of its key components, and how to set up your environment to start contributing. We’ll walk through the contribution process, tackle curated GitHub issues, and provide guidance tailored to your skill level. Whether you're interested in improving code, documentation, or community engagement, this session offers a great way to make an impact while learning valuable skills. Let’s build cert-manager together!

This is a dump of the first good issues we have at the moment in cert-manager/cert-manager.

They might not be super interesting... If we get accepted, let's work further on curating "actually good" first issues :D

[maelvls]

It was accepted!

Few suggestions!

[maelvls]

talked about today:

• @hawksight to create a spreadsheet with good issues
• @erikgb talked about the dev environment, do we need to review on site, "staging" repo?
• @maelvls Focus of the session would be to learn how to set up to get started contributing rather than opening their first PR since we only have 1 hour and 15 minutes. Explain that in the introduction: what we want to get out of this.
• @erikgb described the session as "for the Crossplane session, you had to come early to get a chair, we set up the dev environment, but it was interesting to learn about the project, maintainers were roaming the room, it felt like a classroom, and there was a nice presentation. It was crowded, we came earlier, skipped the session earlier to reserve a spot. We chose the Crossplane session because we had started investigating using Crossplane in our company; we wanted to learn how the project was set up. We also came with some issues we were motiveded to get fixed. People want to get in touch with the maintainers."
• @erikgb mentioned Codespace for the cert-manager project? Yes, it would be great to have a configuration file that sets up Codespace. Folks will be running it from their fork.
• @maelvls to prepare a "Setting up your dev env for cert-manager on macOS" video + tutorial so that we speed up the beginning of the session.
• @maelvls to look up examples of presentations that were given in past contribfest session.
  • maybe structure of the project
• @wallrj suggested pointing people to cmctl, cmctl status breaks in many ways. Richard to lookup those issues and putting them in Peter's spreadsheet.

[maelvls]

I struggled a bit with running make check (fixed the bug in #1644), but it should be good to go now.

[maelvls]

Discussed today:

• @hawksight created a spreadsheet with the good first issues: https://docs.google.com/spreadsheets/d/1zThfUB22HHdHAiRvS3ctbj4Da7j30imnUleURjxTYE0/edit?gid=1532279653#gid=1532279653
• @maelvls to propose @wallrj to do the presentation.
• Erik will prepare a devcontainer image.
• Mael will start the tutorial when he comes back on 28th Feb (unless @wallrj wants to start before that). We will decide by then if the devcontainer approach could be used in the tutorial.

@hawksight Sorry about the list I had originally put in the document. I'm not sure why ChatGPT hallucinated like that...

I've re-made the list using the following:

gh issue list --repo cert-manager/cert-manager --search 'is:open sort:reactions-+1-desc label:"good first issue"' --json url,title,reactionGroups

then given to ChatGPT's o4 with the following prompt:

Make a markdown list using the following example:

- **[#6622](https://github.com/cert-manager/cert-manager/issues/6622)**: Improve logging clarity in ACME challenge solver.

Using the following data:

Result:

• #6269: Allow hardcoded JKS and PKCS#12 passwords. Done
• #2334: Add network policy allowance into documentation.
• #3103: Adding probes to the cert-manager pods.
• #7184: Helm chart: add ability to add appprotocol to port in service.
• #7344: Support temporary certificates with annotated gateways.
• #7459: FindZoneByFqdn does not honor SOA TTL.
• #7062: cainjector shows usages and non json output, if error appears.
• #7196: cert-manager incorrectly relies only on http status errors to update order error reason.
• #7101: Add global image repository value to helm values to facilitate private repo and eliminate need to maintain individual repo image paths.

Anyone should be able to view the list here: https://docs.google.com/spreadsheets/d/1zThfUB22HHdHAiRvS3ctbj4Da7j30imnUleURjxTYE0/edit?usp=sharing

Would you like me to commit it to this document, in place of the list of items?
I included what you pulled out.

Triage of them is yet to be added.

@maelvls - I have revised your efforts to generate a CSV we can generate as needed:

My generate.zsh:

#!/bin/zsh

repos=(cert-manager trust-manager approver-policy csi-driver csi-driver-spiffe istio-csr base-images google-cas-issuer makefile-modules issuer-lib helm-tool cmctl)
total_count=0
timestamp=$(date -u +%Y%m%d-%H%M%S)
output_file="$timestamp-cert-manager-org-good-first-issues.csv"
header_string="repo,issue_number,url,title,createdAt,updatedAt"

printf "Starting initial file at: $PWD/$output_file\n"
echo '"repo","createdAt","number","title","updatedAt","url"' > $output_file

for repo in ${repos[@]}; do
  issues=$(gh issue list --repo cert-manager/$repo --state open --search 'label:"good first issue"' --json number,url,title,createdAt,updatedAt)
  issue_count=$(echo $issues | jq '. | length')
  total_count=$((total_count + issue_count))
  if [[ $issue_count == 0 ]] ; then
    printf "Skipping repo: cert-manager/$repo as it has $issue_count 'good first' issues...\n"
    continue
  else;
    echo $issues | jq -r '(map(keys) | add | unique) as $cols | map(. as $row | $cols | map($row[.])) as $rows | $cols, $rows[] | @csv'  | awk -v repo=$repo 'NR>1 {print repo","$0}' >> $output_file
    printf "Completed repo: cert-manager/$repo as it has $issue_count 'good first' issues...\n"
  fi

done

printf "Script complete with $total_count 'good first' issues found\n\n"
cat $output_file
printf "\n"

An example output:

I have uploaded the results to the same google sheet as before.

Now we just need to triage issues to ensure we have some more "good first issue"'s! Ask you can see there are only 10, across a whole bunch of repos. I will attempt to bring this to standup next week. Maybe Triage party does this for us.. but I hope this is somewhat useful.

Also we need to get this page live, time is ticking.

[hawksight]

I think we need to get this up, and then we can promote it to people.
Looks good, left a suggestion on issues.
