Some useful k8s tools to simplify your life using old great bash

OneFit K8s-tools (samples)

Deploy: This tool allows you to build Kustomize overlays with placeholders, deploy to google cloud, with status monitoring. Watch: This tool allows you to watch local files and rsync it with remote K8s container.

Setup

Install Google Cloud SDK

curl https://sdk.cloud.google.com | bash
exec -l $SHELL
gcloud init

Install Kubernetes or enable Kubernetes via Docker Settings

brew install kubernetes-cli

Install Envsubst

We use it for filling placeholders

brew install gettext

For MacOS it should be already installed, so need only to link:

brew link --force gettext

Install Kustomize

We use it for reusability of K8s configurations

brew install kustomize

Install fswatch

We use it for the watcher syncing files from local to remote k8s

brew install fswatch

Install GNU-Core-Utils

We use it for timeout command (gtimeout for mac)

brew install coreutils

Deploy

The following command will generate a new environment in Google Cloud

./bin/k8s-deploy kubernetes/overlays/ENV/APP \
-n NAMESPACE \
-t CONTAINER_REGISTRY_TAG

APP is the name of the overlay, ENV is dev or production NAMESPACE can be your name (also in URL), and TAG is version (e.g. 1.0.0).

Sync Watcher:

Our current structure supports easy syncing between local dev files and remote cloud files. For your convenience it is recommended to place it in your PATH:

export PATH=$PATH:PATH/TO/CLOUD/REPO/BIN

To make this permanent, add it to your ~/.bashrc or ~/.bash_profile and source it.
