Freeze your charts in the wished versions. Helm freeze helps you to declare the charts you want to use in a desired version and download them locally. This to freeze/lock them directly in your Git repository.
The advantages are:
- Follow GitOps philosophy
- Know exactly what has changed between 2 charts version with a
git diff - One place to list them all
- Works well with monorepo
- Declarative configuration (YAML file)
- Supports git repositories in addition to charts repositories
On Mac, you need to have brew installed, then you can run those commands:
brew tap Qovery/helm-freeze
brew install helm-freezeAn AUR package exists called helm-freeze, you can install it with yay:
yay helm-freezeYou can download binaries from the release section.
To use helm-freeze, you need a configuration file. You can generate a default file like this:
helm-freeze initA minimal file named helm-freeze.yaml will be generated. Here is an example of a more complex one:
charts:
# Chart name
- name: cert-manager
# Chart version
version: v0.16.0
# The repo to use (declared below in the repos section)
repo_name: jetstack
# No destinations is declared, the default one will be used
comment: "You can add comments"
- name: fluent-bit
repo_name: lifen
version: 2.8.0
# If you temporary want to stop syncing a specific chart
no_sync: true
- name: nginx-ingress
# No repo_name is specified, stable will be used
version: 1.35.0
# Change the destination to another one (declared in destinations section)
dest: custom
- name: pleco
repo_name: git-repo
# When using a git repo, chart_path is mandatory, you need to specify the chart folder path
chart_path: /charts/pleco
dest: custom
# Set git reference
version: 5e05faddb0fde1f5ddd822c3d3ba72925f094e67
repos:
# Stable is the default one
- name: stable
url: https://charts.helm.sh/stable
- name: jetstack
url: https://charts.jetstack.io
- name: lifen
url: https://honestica.github.io/lifen-charts
- name: git-repo
url: https://github.com/Qovery/pleco.git
# If you want to directly use a chart folder in a git repo, set type to git
type: git
destinations:
- name: default
path: /my/absolute/path
- name: custom
path: ./my/relative/pathThen use sync arg to locally download the declared versions, here is an example:
$ helm-freeze sync
[+] Adding helm repos
-> stable
-> aws
-> git-repo
[+] Updating helm repos
[+] Downloading charts
-> stable/nginx-ingress 1.35.0
-> stable/prometheus-operator 8.15.12
-> stable/elasticsearch-curator 2.1.5
-> aws/aws-node-termination-handler 0.8.0
-> aws/aws-vpc-cni 1.0.9
-> git/pleco 5e05faddb0fde1f5ddd822c3d3ba72925f094e67
Sync succeed!If you update a chart, launch sync and you'll be able to see the differences with git diff.
