What is Fux?
Flux is a tool for keeping Kubernetes clusters in sync with sources of configuration (like Git repositories), and automating updates to configuration when there is new code to deploy. It’s open source and you can read more about it on the GitHub repo. Looking for a turial on how use this? Check out this video on how to use SOPS and Age for your Git Repos!
Updating Flux
We’re going to use curl so you’ll want to be sure you have it install
curl -V
This should return something simiar to the following
curl 7.68.0 (x86_64-pc-linux-gnu) libcurl/7.68.0 OpenSSL/1.1.1f zlib/1.2.11 brotli/1.0.7 libidn2/2.2.0 libpsl/0.21.0 (+libidn2/2.2.0) libssh/0.9.3/openssl/zlib nghttp2/1.40.0 librtmp/2.3

sudo apt update && sudo apt install curl
Then we’ll want to download the latest Flux binary by running
curl -s https://fluxcd.io/install.sh | sudo bash
Then we’ll want to be sure it’s installed properly by running
flux -v
This should return something simialr to the following
flux version 0.39.0
Next we’ll need to locate our gotk-components.yaml file for flux in our git repo. For example, mine lives in clusters/cluster-01/base
clusters
├── cluster-01
│ ├── base
│ │ └── flux-system
│ │ └── gotk-components.yaml
One you locate gotk-components.yaml we’ll patch it by using the following command
flux install --export > clusters/cluster-01/base/flux-system/gotk-components.yaml
After this file is updated, you can check to be sure it updated the correct file by running
git diff
You should see something like the following
diff --git a/clusters/cluster-01/base/flux-system/gotk-components.yaml b/clusters/cluster-01/base/flux-system/gotk-components.yaml
index 79576f0f..9c26b708 100644

if you see something other than the original gotk-components.yaml being updated, you might want to check the location of the file and try again.
Once this is updated, you can simply commit and push this up and let GitOps do the rest!
git add .
git commit -m "feat(flux): Upgraded flux to 0.39.0" # replace with your verion
git push
