lukeplausin / upload_historical_charts
Last active May 30, 2024 09:26
Upload all historical helm chart versions from a chart git repository history. If you didn't use a chart repository before but you do now, well this chart can help you upload your back catalogue.
#!/usr/bin/env zsh
# This script assumes that you store all your charts in a single repo
# under a single folder called charts-folder. It will go back through previous versions
# of the code and upload all of them into your chart registry.
# This script assumes that you have updated the chart version in `Chart.yaml`
# whenever a change has been made in the chart. If this is not the case, you can
# switch off version checking by disabling the check on line 54.

Install ArgoCD lovely plugin via helm values.yaml file configuration
# Ah yes, the lovely, undocumented, and not-at-all-irrationally-difficult-to-understand ArgoCD method of chart customisation - plugins...
# If you are struggling to install the "lovely" plugin (or any plugin for that matter) with the ArgoCD Helm chart, this Gist could help you.
# Include this values config file as part of a Helm/Helmfile values argument to include the "lovely" plugin in your ArgoCD deployment.
# "Lovely" includes several popular tools for helm chart management, including the brilliant Helmfile, which itself includes
# "Vals" for secrets management.

lukeplausin / undelete_gcs_objects.py
Created January 26, 2024 12:55
This gist describes how to undelete files in GCS while retaining most of the metadata. I couldn't find any examples of how to do this other than in the UI. GCS doesn't seem to use delete markers like AWS. If anyone knows a better way please say so.
# This gist describes how to undelete files in GCS while retaining most of the metadata.
# GCS doesn't seem to use delete markers like AWS. If anyone knows a better way please say so in the comments.
# I couldn't find any examples of how to do this other than in the UI.
# GCS documentation doesn't seem to include instructions for restoring versioned objects in python, but I found
# that this method works. Confusingly they use terms like version, generation, and revision interchangably in
# the documentation. I couldn't understand how object deletion works on versioned buckets.

Export terraform cloud state files with history to a GCS bucket
# This example shows how you can export your Hashicorp Terraform Cloud state files out of
# Terraform Cloud and into a bucket storage provider, with the full history.
# This example assumes that you have object versioning enabled on your bucket storage.
# The example is written for using Google Cloud Storage, but can be adapted for any storage provider.
# Before you run the code, you need to generate an API token in Terraform Cloud, and export it as "TFE_TOKEN" in your shell.
# pip install terrasnek google-cloud-storage ipython

Last active October 21, 2024 15:17
Automatically configure AWS SSO configuration file for all available accounts and roles
#!/bin/bash -e
# How to use this script:
# 1. Follow these instructions to configure a single AWS account to do initial login with SSO
# https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-sso.html
# 2. Export AWS_PROFILE=... and then run "aws sso login" to get an SSO token
# 3. Once signed in with AWS SSO, run this script to automatically list out all the other accounts and roles and add them to your config file
# If you want to filter roles / accounts in the process, or validate config before committing it, you can customise the script to do this.

Clean up merged git branches
#!/bin/zsh
# Do merged git branches clutter up your local machine?
# This handy script can automatically clean them up for you.
# To install - put the script somewhere on the filesystem and add a source command to your .bashrc / .zshrc
# e.g. - 'source ~/code/scrapbook/cleanup_git.sh'
# When the script is sourced you will get two commands -
# "gitclean" - delete merged branches in current folder (with prompt)

Copy data from local filesystem into a pod in kubernetes
# If your pod container doesn't have bash in the path, you might need to replace `bash` with `/bin/bash/`, `/bin/sh` or `/bin/ash`.
# Simple string from the command line - puts the literal text 'AAA' into a new file /tmp/test.txt
echo 'AAA' > kubectl -n MyNamespace exec -ti $my_pod_id -c my-pod-container -- bash -c 'cat - > /tmp/test.txt'
# Copy / inject a file from the local filesystem into a new file in the pod in the remote kubernetes cluster
kubectl -n MyNamespace exec -i $my_pod_id -c my-pod-container -- bash -c 'cat - > /tmp/file.txt' </my/input/file.txt
