Base docker image for all of my NodeJS apps.
In Dockerfile:
FROM mersocarlin/docker-node
# create app directory in container
RUN mkdir -p /app
# set /app directory as default working directory
WORKDIR /app
# copy package.json, yarn.lock (or package-lock.json) and install dependencies
ADD package.json yarn.lock /app/
# --pure-lockfile: Don’t generate a yarn.lock lockfile
RUN yarn --pure-lockfile
COPY . /app/
# expose container port
EXPOSE 3001
CMD [ "yarn", "test" ]
docker build -t mersocarlin/docker-node:20-alpine
git tag v20-alpine
docker tag mersocarlin/docker-node:20-alpine mersocarlin/docker-node:latest
docker push mersocarlin/docker-node:latest
git push origin --tags
