setup

npm i angelscripts-stem-docker --save-dev

usage

build a stem skeleton cell

$ cd cells/myCell
$ edit ./Dockerfile
$ npx angel docker-build

Dockerfile

docker-build command accepts Dockerfiles as templates and replaces everything within #deps> & #<deps markers with cell's package dependencies.

Here is example file:

# Dockerfile context is repo's root
# Dockerfile is a template
# usage 
# $ cd cells/cell89 && npx angel docker build ./docker/Dockerfile

FROM node:16-alpine as base
RUN apk update && apk upgrade
RUN apk add --no-cache bash git openssh

ARG mode='production'
ARG cellName='cell89'
ARG cellRoot='cells/cell89'

ENV NODE_ENV $mode

#deps>
#
# cell package dependencies will be inserted here as 
# COPY ./packages/package/ /repo/packages/package/
# RUN cd /packages/package/ && npm install --$mode
# 
#<deps

COPY ./dna/ ./repo/dna/
COPY ./$cellRoot/ /repo/$cellRoot/
RUN cd /repo/$cellRoot/ && npm install --$mode

WORKDIR /repo/$cellRoot/
CMD node index.js

compose up & down

docker-compose command uses docker-compose.yaml from cell's DNA so that all DNA related features are supported and the file can be used as a template. The command prefills image, ports & volumes using cell's DNA as well as dependent packages.

$ cd cells/myCell
$ edit ./dna/docker-compose.yaml
$ npx angel docker-compose up
...
$ npx angel docker-compose down

docker-compose.yaml

# the compose file is applied with repo's root as context
# usage:
# $ cd cells/myCell && npx angel docker-compose
version: "3.4"
services:
  myCell:
    # if not set
    # image: 
      # auto populated as node alpine
    # ports: 
      # auto populated using cellDNA.port in _development mode if present
    # volumes: 
      # auto populated with repo/dna, repo/cell, repo cell's packages
    working_dir: "/repo/@{cells.myCell.cwd}"
    environment:
      NODE_ENV: development
      CELL_MODE: _development
    command: npm run dev
    labels: 
      route: '/myCell'

publish image

docker-publish command is a shorthand to build, tag and publish the Dockerfile. It uses cell's dna docker-registry property in order to publish at remote container registry.

$ cd cells/myCell
$ npx angel docker-publish
