angelscripts-k8s-development v6.2.0

angelscripts-k8s-development

organic-angel scripts for development within k8s clusters.

Works with angelscripts-dockerbuild.

prerequirements

• kubectl
• angelscripts-dockerbuild

setup

$ npm i angelscripts-k8s-development --save
$ edit dna/cells/my-cell/development.yaml

usage

Notes:

• namespace value if not provided will be sourced from process.env.USER variable.

example

$ cd ./my-stem-skeleton-2-1-based-project
$ cd ./cells/myCell
$ angel k8sd up -- nodemon index.js
$ angel k8sd down

The above example will start myCell for development by building its base image of dependencies and its staged in git source code.

It will use cells.myCell.development as k8s configuration to bootstrap (or seek existing) deployment.

The container will be started with command nodemon index.js within namespace with value of process.env.USER.

angel k8sd up :namespace :branchName -- :runCMD

Creates (or re-uses) a k8s deployment within namespace using branchName to drain k8s configuration from the current working cell dna.

Stopping the command doesn't stops the container. The command starts (and stops when stopped) local synchronizer and logs streaming.

angel k8sd down :namespace :branchName

Stops already running container via angel k8sd up

angel k8sd enter :namespace

Enters as remote bash session within already running container via angel k8sd up.

angel k8sd start :namespace :branchName

Applies given cells.<cell>.<branchName> at k8s and uses imageTag without namespace applied.

This is useful to bootstrap latest production released containers within the development namespace with development mode applied.

angel k8sd delete :namespace :branchName

Deletes given cells.<cell>.<branchName> from k8s.

angel k8sd exec :namespace -- :runCMD

Executes runCMD at k8s running container within namespace

angel k8sd logs :namespace

Prints last 10 lines and streams the respective container logs from the cell

angel k8sd sync :namespace

Monitors for file changes within the repo's cells/node_modules and current working cell directories and uploads any to respective container at k8s.

angel k8sd buildbase :branchName :namespace

Creates a base container image using angel buildbase script from angelscripts-dockerbuild.

This is used by angel k8sd up as base layer to bootstrap respective cell without installing any of its depdencies.

angel k8sd reversetunnel :namespace -- :runCmd

Uses current working cell.dna.development branch to create a deployment (and optionally service) having datawire/telepresence-k8s:0.104 image set.

Once the deployment is running establishes reverse tunnel to its pod via telepresence (expected to be pre-installed).
