peh3

peh (PNDLM Environment Helper) is a tool by PNDLM for building simple, reliable, reusable software development environments based on Docker Stack.

Philosophical goals—

• Minimize pre-requisite installation requirements on dev machines
• Limit custom tooling and abstraction; directly leverage great off-the-shelf tooling wherever possible
• Remain dev/deploy platform agnostic

Components are—

• A Golang CLI library (https://github.com/pndlm/peh/peh3) with common various docker/npm/dev-ops functions, commands and shortcuts
• A project-template used to kick off new software project git repositories that are based on peh
  • Project-specific CLI utility— the template contains a utility app in /peh/src that ingests the peh3 library and is customizable to whatever the project needs
• A global helper utility that allows one to type peh at the command-line within any peh project and run its specific CLI utility

Setup

Install the base pre-requisites—

• Docker Desktop — https://docs.docker.com/desktop/install
  • For Linux, strongly recommend following the Digital Ocean instructions for your distribution
• Go — https://go.dev/dl

Install the global peh helper on your development machine—

GOPROXY=direct go install github.com/pndlm/peh/helper/peh@latest

# If Go isn't already in your path, add it
# Please interpret for the shell of your choice
echo 'export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin' >> ~/.bashrc

After a shell restart or reboot, you should now be able to run peh at your command-line to see a list of available commands.

Adding peh3 to an existing peh2 project

• Copy a fresh peh directory into the project:

cd projectdir
npx degit pndlm/peh/project-template/peh peh --force

• Add use ./peh/src to go.work file as necessary
• Grep and replace all instances of pndlm.com/example-project with a customized name e.g. client.com/appname/peh
• Install dependencies:

cd peh/src
go get github.com/pndlm/peh/peh3
go work sync

Developing on peh3 library

To develop and test changes to peh3 library alongside of a consuming project, check out this repository next to your active project and review/uncomment the replace directive at the bottom of your project's /peh/src/go.mod file.

WIP

• New project creation instructions

# don't forget to install the latest version of the library....
GOPROXY=direct go get github.com/pndlm/peh/peh3

• Add docker-compose.yaml and README to project-template
• Test fully new installation
• Make creating a new installation a command on peh helper itself ?
• Allow use of both docker compose & docker stack ?
