  • Patching a kubernetes object with kubectl patch and a patch file

    kubernetes kubectl patch file

    We can use the kubectl patch command with the -p option to update an existing kubernetes object:

    $ kubectl patch sc gp2 -p '{"allowVolumeExpansion": true}'
storageclass.storage.k8s.io/gp2 patched

    When the patch is small is a very convenient way of patching it but as the patch grows it becomes less convenient

  • Kubernetes: Apply parts of a manifest by labels

    2 min read

    kubernetes kubectl selector apply

    Sometimes we might have a manifest file with a lot of objects in it but we don't really need them all. We can use it's labels to install just the objects that have a specific label.

    minikube docker colima apple M1 arm64 apple sillicon

    If you try to install minikube on an Apple Sillicon (such as Apple M1, M2...) you will face that some hypervisors doesn't support arm64 yet. Using Docker Destop, on the other hand, has recently changed it's license so it might not be suitable to you

    $ minikube start
😄  minikube v1.26.1 on Darwin 12.5.1 (arm64)
✨  Automatically selected the parallels driver. Other choices: ssh, qemu2 (experimental)

❌  Exiting due to DRV_UNSUPPORTED_OS: The driver 'parallels' is not supported on darwin/arm64

$ minikube start --driver docker
😄  minikube v1.26.1 on Darwin 12.5.1 (arm64)
✨  Using the docker driver based on user configuration

💣  Exiting due to PROVIDER_DOCKER_NOT_RUNNING: "docker version --format -" exit status 1: Cannot connect to the Docker daemon at unix:///Users/jordiprats/.rd/docker.sock. Is the docker daemon running?
💡  Suggestion: Start the Docker service
📘  Documentation: https://minikube.sigs.k8s.io/docs/drivers/docker/

    There are several alternatives to Docker Desktop but the one that I found more convenient and easier to install is Colima
