common-build-scripts

Common build scripts and functions that can be invoked directly or via docker.

Quickstart:

Install locally with:

# The URL below is mapped to the raw script stored on the `main` 
# branch of this repository at scripts/install-common-build-scripts.sh.

echo $(source <(curl -s https://uwiam.page.link/install-build-scripts))

How to Use This

You can install these scripts on your local machine to make them avaialable to your developer workspace, or you can simply invoke the docker container.

. . . from Github Actions

You can run your actions directly on the vended docker image. The release and latest tags will always be the most recently published release.

You can also select a version from the past. Check the docker repository for more information.

Run a single command

# in your workflow.yml

steps:
  - uses: actions/checkout@v2
  - uses: docker://ghcr.io/uwit-iam/common-build-scripts:release
    with:
       args: calculate_string_fingerprint "hello!"

Run an entire script that invokes the commands

#!/usr/bin/env bash

fingerprint=$(calculate_paths_fingerprint assets)
link=$(slack_link https://fingerprints.com/$fingerprint "click here")
slack_message="To view this fingerprint, $link!"
set_ci_output slack-message "$slack_message"

# in your workflow.yml

steps:
  - uses: actions/checkout@v2
  - uses: docker://ghcr.io/uwit-iam/common-build-scripts:release
    with:
       args: ./build_scripts/foo.sh

. . . anywhere!

Install to your environment

The following one-liner will install the build scripts to your local ./build-scripts directory. It is recommended to defer to default behavior, which installs this in your repository root, instead of system-wide.

You can control the build directory with the --dirctory/-d argument, and set the version with the --version/-v argument.

# The URL below is mapped to the raw script stored on the `main` 
# branch of this repository at scripts/install-common-build-scripts.sh.
echo $(source <(curl -s https://uwiam.page.link/install-build-scripts))

If you want to control which installer you use, you can use the URL Format:

https://raw.githubusercontent.com/UWIT-IAM/common-build-scripts/REF/scripts/install-common-build-scripts.sh

where ${REF} is the branch or other resolvable reference you want to use. (Mostly this is important if you want to install and test a new release before it is merged.)

Run using docker

Run a single command:

docker run -it ghcr.io/uwit-iam/common-build-scripts:release calculate_string_fingerprint "Hello!"

Mount your repository on the docker image to perform your builds:

docker run -it -v $PWD:/source ghcr.io/uwit-iam/common-build-scripts:release /source/foo.sh

Extend the Docker image:

This example installs the build scripts onto the UWIT-IAM poetry image, then installs project dependencies:

ARG CBS_VERSION=release
FROM ghcr.io/uwit-iam/common-build-scripts:${CBS_VERSION} AS build-scripts

ARG POETRY_VERSION=latest
FROM ghcr.io/uwit-iam/poetry:${POETRY_VERSION} AS builder-base
workdir /build
COPY --from=build-scripts /builder /build-scripts
COPY pyproject.toml poetry.lock ./
RUN poetry install && /builder/scripts/do_work.sh
