I recently noticed long social slugs were still breaking my BlueSky app poster when updating this blog.

In this post we debug then update the Python code to check for size and trim. We also build out helm charts, Github workflows that leverage my on-prem Harbor CR (in a public shared repo). The result is an expose RESTful endpoint anyone can use to post to BlueSky

Checking the errors

I noted that a post still was blocked

<!doctype html>
<html lang=en>
<title>500 Internal Server Error</title>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.</p>

I was able to test and replicate locally

$ cat bsky.payload2.json
{"USERNAME": "isaacj.bsky.social", "PASSWORD": "xxxxxxxxxxxxxx", "TEXT": "When one builds a poor man's data center in the basement with discarded and obsolete old tech, there are bound to be failures.

We even have Phantom pages and laptop batteries that are going full marshmallow man (stayin puft).", "LINK": "https://go.tpk.pw/qzpq5"}

$ curl -X POST https://bskyposter.steeped.space/post -H 'Content-Type: application/json' -d @bsky.payload2.json

I went to the cluster to check the logs of the container

We can see that “300” limit is hitting us again

Invalid app.bsky.feed.post record: Record/text must not be longer than 300 graphemes

Just to show that was the cause, I posted a revised entry I manually shortened.

$ cat bsky.payload2.json
{"USERNAME": "isaacj.bsky.social", "PASSWORD": "xxxxxxxxxxxxxx", "TEXT": "When one builds a poor man's data center in the basement with discarded and obsolete old tech, there are bound to be failures.  Today I wanted to share a few find-and-fix moments maintaining a functioning home lab.  From MinIO and NAS Updates to disk remediation...", "LINK": "https://go.tpk.pw/qzpq5"}

$ curl -X POST https://bskyposter.steeped.space/post -H 'Content-Type: application/json' -d @bsky.payload2.json
{"LINK":"https://go.tpk.pw/qzpq5","TEXT":"<atproto_client.utils.text_builder.TextBuilder object at 0x7f77b87d2a90>","YOU ARE:":"Isaac Johnson"}

which worked

I’m realizing it would be far better to move the logic into the containerized app then try and keep fiddling with my Github actions

Updating the BS Poster App

I’ll clone it locally

First, I don’t want to have to build the Docker container locally over and over.

Beyond that, Dockerhub’s rate limiting is getting really bad so I want to publish to Github CR or perhaps a public endpoing in my own CR.

Let’s look at the Github Workflow I just created in .github/workflows/container-build.yml

          docker images
          echo $CR_PAT | docker login harbor.freshbrewed.science -u $CR_USER --password-stdin
          # SHOW THE COMMAND
          echo "IF we were on main, we would: docker push $FINALBUILDTAG"

          CR_PAT: $
          CR_USER: $

                - "project:$"
                - "branch:$"
      - run: echo "🍏 This job's status is $."

Since I want to use my public CR, I’ll use the existing Forgejo user that has “developer” permissions to push containers there

And I can the set my secrets, namely CR_PAT, CR_USER and DATADOG_API_KEY

Lastly, before I test this flow, it assumes I put the primary destination CR as a comment in the last line of my Dockerfile. I’ll parse the version from here (it allows builds this way)

# Use an official Python runtime as a parent image
FROM python:3.9-slim

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into the container at /app
COPY . /app

# Install any needed packages specified in requirements.txt
RUN pip install -r requirements.txt

# Make port 5000 available to the world outside this container
EXPOSE 5000

# Define environment variable
ENV NAME=World

# Run app.py when the container launches
CMD ["python", "app.py"]

#harbor.freshbrewed.science/library/pybsposter:0.0.1

Time to see if it works

I can see it fired off a workflow action

I can now see the pull command

docker pull harbor.freshbrewed.science/library/pybsposter@sha256:706b07f0f80917fa35577d3ba80e9053b225e2d4604a1374480aee8eb69aeaee

docker pull harbor.freshbrewed.science/library/pybsposter:0.0.1

I’ll test by editting my deployment to use the image

And i can see the rotated pod is using the public image

builder@DESKTOP-QADGF36:~/Workspaces/pybsposter$ kubectl get pods | grep pybs
pybsposter-5f6667dc8c-269rh                          1/1     Running     0                60s
builder@DESKTOP-QADGF36:~/Workspaces/pybsposter$ kubectl get pods pybsposter-5f6667dc8c-269rh -o yaml | grep -i image:
  - image: harbor.freshbrewed.science/library/pybsposter:0.0.1
    image: harbor.freshbrewed.science/library/pybsposter:0.0.1

I used Copilot and Gemini Code Assist and they both suggested the same updated code:

    # Calculate the total length of text and link 
    total_length = len(text) + len(link)
    if total_length > 300:
        text = text[:(300 - len(link))]

You can see these next changes which include adding a “latest” tag, updated notes in the README.md and deployment.yaml

I can see both tags were pushed

I’ll now update the Github Workflow to build and push a helm chart:

I won’t list out the charts, but you can see them here

And I can Github Actions workflow worked:

One last change - if I plan to share this, ingress should be disabled by default.

Testing

Let’s use a longer post. I was a bit wordy just see a content I know would exceed the limit

$ cat /home/builder/Workspaces/jekyll-blog/bsky.payload2.json
{"USERNAME": "isaacj.bsky.social", "PASSWORD": "xxxxxxxxx", "TEXT": "Looking forward to taking the kiddos to the St. Paul Ice Fishing Show today (or this weekend).  I keep checking the temps and I hope to get down to the local small lake to test the thickness. I tend to use a pop-up insulated tent but one of these years I hope to get a proper ice-house", "LINK": "https://www.stpaulicefishingshow.com/"}

That worked, but I wonder if I should add ellipses?

Can I just take a moment to say how much I like Gemini Code Assist? I asked to add the “…” and I planned to account for the extra space by dropping 300 to 297 but I noticed it already accounted for that when it returned the updated Python code

I’ll update for that (and add a space)

Since my chart uses the image pull policy of “IfNotPresent” and a tag of “latest”, I’ll want to force it to use a versioned tag to force it to update now

I’m not going to edit it further, even if it seems odd to trim a status update.

Summary

We updated the BlueSky app to use a Helm Chart and fixed it to automatically trim larger posts. This should prevent our Github Posts from ever dropping due to size issues.

We also changed the Github repo to use Github Actions and push to my self-hosted Harbor CR in a public share (as well as an OCI Helm chart). Thus anyone can now helm install with just this one-liner:

$ helm install pybsposter oci://harbor.freshbrewed.science/library/pybsposter --version 0.1.1

I just overrode some values for my local install

$ helm get values pybsposter
USER-SUPPLIED VALUES:
image:
  tag: 0.0.4
ingress:
  enabled: true

But all the values

$ helm get values --all pybsposter
