README: xlscal-to-pdfics

1 Purpose

Take an Excel file that looks like:

/	<
1/1/2019	Event 1
1/2/2019	Event 2
1/3/2019	Event 3

as an upload and produce a PDF calendar, one month for page, and an ICS file that can be imported into calendars with that data on them.

buff = BytesIO()
doc = SimpleDocTemplate(buff, pagesize=letter)

doc.build(elements)
response.write(buff.getvalue())
buff.close()
return response

Maybe hosting?

This didn’t work, though, with the error:

Which is, according to search results, not uncommon.

You should have a Microsoft XLSX file that has a list of dates in Column A and
a list of events in Column B. Click the "Browse" button below and locate that
file. Press the "Create Zip file of PDF and ICS file" button and you will be
prompted to open or save a Zip file. You should save it. In that Zip file will
be a PDF file with a monthly calendar for each month that has an event and an
ICS file that can be imported into your calendar program (Microsoft Outlook,
MacOS Calendar, etc.)

2.2 DNS

At https://dcc.godaddy.com/manage/acaird.com/dns click “Add”, select “A” as the type (an A record) hostname, xxxxxx, and the IP address above, xx.xx.xx.xx.

dig xxxxxx.acaird.com

;; global options: +cmd

3 Project Plan

[X] Get Docker-ized Flask app that accepts the upload of an Excel file into memory, turns it into a Python data object, and prints an HTML page
[X] Produce a PDF calendar for each month that has data and make them available for download or initiate downloads for them or something
[X] Produce an ICS file with the data and make it available for download or initiate a download or something

3.1 Nice-to-have

[ ] put a timestamp on the PDF files saying when they were generated
[X] better error handling in the code; right now it just 500s when it doesn’t like something
- [X] get the basics
[X] some better styling so the page is prettier and has more instructions and stuff
- [X] use flask_bootstrap and some lame styling
[ ] password protect the whole thing

3.2 Deployment

Kubernetes
Google Cloud run: https://alexolivier.me/posts/deploy-container-stateless-cheap-google-cloud-run-serverless

4 Github Automated Build and Push

Cool documentation at https://help.github.com/en/actions/reference/workflow-syntax-for-github-actions

   # This workflow will build a docker container, publish it to Google Container Registry, and deploy it to GKE.
   #
   # To configure this workflow:
   #
   # 1. Ensure that your repository contains the necessary configuration
   # for your Google Kubernetes Engine cluster, including deployment.yml,
   # kustomization.yml, service.yml, etc.
   #
   # 2. Set up secrets in your workspace: GKE_PROJECT with the name of
   # the project, GKE_EMAIL with the service account email, GKE_KEY with
   # the Base64 encoded JSON service account key
   # (https://github.com/GoogleCloudPlatform/github-actions/tree/docs/service-account-key/setup-gcloud#inputs).
   #
   # 3. Change the values for the GKE_ZONE, GKE_CLUSTER, IMAGE,
   # REGISTRY_HOSTNAME and DEPLOYMENT_NAME environment variables (below).

This requires a Github secret for the project.

I made this following the instructions at https://cloud.google.com/iam/docs/creating-managing-service-account-keys#iam-service-account-keys-create-console

To do this via the gcloud command line, first type:

gcloud iam service-accounts list --project $PROJECT_NAME

then create a token by typing:

gcloud iam service-accounts keys \
	   create $PATH_TO_KEY_FILE \
	   --iam-account $ACCOUNT_EMAIL_FROM_PRIOR_COMMAND \
	   --project $PROJECT_NAME

this will create a file in $PATH_TO_KEY_FILE.

That file needs to be base64-encoded and copied to the Github project’s secrets.

Go to the project’s page at Github
From the list of options along the top of the project (below the title) click “Settings” then from the menu on the left click “Secrets”
Click Add Secret, set the Name to GCR_KEY and the Value to the base64-encoded version of $PATH_TO_KEY_FILE. Click the “Add Secret” button

Now Github can access your Google project; there may be better security that this, but 🤷

Add the YAML file to =$PROJECT_ROOT/.github/workflows/google.yml

Now when you push a branch, it will get built, tagged with the branch version and the latest version.

This still won’t make that version show up in Google Cloud Run when you access your application. For that, there is more…

4.1 To Do

[X] make authentication file using gcloud command line
[ ] set up builds to only happen on new tags, and use tag as image tag
[ ] actually re-deploy Google Cloud Run image when that happens

5 Investigating a `gcloud run` instance

Many fun commands.

List the services

gcloud run services list --platform managed

List the projects:

gcloud run revisions list --region us-central1 --platform managed

List the Kubernetes details for a project

gcloud run revisions describe --region us-central1 --platform managed cal-pdf-ics-00003-fal

Delete an image with the (literal) tag GITHUB_REF (because I can’t work shell variables); the --quiet flag prevents the confirmation prompt (weird name for that behavior, right?)

gcloud container images delete gcr.io/cal-pdf-ics/cal-pdf-ics:GITHUB_REF --quiet

Digests:
- gcr.io/cal-pdf-ics/cal-pdf-ics@sha256:b175bd33fc7af4262154bbac39f7a080f01d7801c0e5599db29ee7913b5e1b62

(Note that the digest listed here is the long version of the digest from the container images list-tags DIGEST column shown above, b175...)

Reporting what image a service is using

   gcloud run revisions describe \
  	   --region us-central1 \
  	   --platform managed \
  	   --format=json cal-pdf-ics-00003-fal | \
  	jq '.spec.containers[].image'

"gcr.io/cal-pdf-ics/cal-pdf-ics@sha256:e1deff5d707dbf56a25450ceeecf8d7d4d6c69db84b5d12adf31b2aba54030ee"

Comparing that to the list of images above, this is the image from “2020-01-18T15:48:33” that is untagged. Also, there might be a better way of finding this information. (lmk @acaird)

Changing what image a service is using to the image tagged :latest

gcloud run deploy cal-pdf-ics \
	     --platform managed \
	     --region us-central1 \
	     --image gcr.io/cal-pdf-ics/cal-pdf-ics:latest

This can take a few tens of seconds to complete with the final output being something like

     Deploying container to Cloud Run service [cal-pdf-ics] in project [cal-pdf-ics] region [us-central1]
     ✓ Deploying... Done.
	✓ Creating Revision...
	✓ Routing traffic...
     Done.
     Service [cal-pdf-ics] revision [cal-pdf-ics-00004-hab] has been deployed and is serving 100 percent of traffic at https://cal-pdf-ics-qzug6go32q-uc.a.run.app

This can then be confirmed by listing the tags for a given image in a project

gcloud container images list-tags gcr.io/cal-pdf-ics/cal-pdf-ics
