DevOps Tools

This Docker image encapsulates the tools I routinely utilize during my coding sessions and while interacting with Kubernetes.

Usage

The sole requirement is having Docker installed. You have the option to assign an alias in your shell to employ this image as a command-line utility, or you can directly SSH into the container to use the tools.

docker run -it --rm \
  -e WORKSPACE=${PWD} \
  -e USER=$(whoami) \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v ${PWD}:/workspace \
  -v $(whoami):/root \
  -w /workspace -P ghcr.io/harrytang/devops-tools:latest ssh-agent /bin/zsh'

Config

To switch to another profile, create a new file under your home directory, e.g. ~/CompanyA.sh, ~/CompanyB.sh and add the following content:

#!/bin/bash
export USER=CompanyX

Then run source ~/CompanyA.sh or . ~/CompanyB.sh to switch to the new profile.
