Yarn on Docker Boilerplate

dockeryarn's Issues

latest.tar.gz versus .yarn-cache.tgz

Did I misunderstood something... or the "latest.tar.gz" we see in this repository is the Yarn cache referenced as ".yarn-cache.tgz" in the Medium article?

Docker run and /tmp/yarn.lock

Hey your article on Medium is awesome! Thanks so much for putting that together!

There must be something I'm misunderstanding or not doing right because when I try and deploy my container via docker run ... it errors out and says "cannot find module".

This is the same build file you're using in the demo minus changing the context to the current folder. (My script lives in $DIR/scripts/build.sh. Dockerfile lives under $DIR/.)

It looks like it's pulling the /tmp/yarn.lock file from my PERSONAL computer, not the container. Is that supposed to be the case?

I believe the same is taking place with /root/.yarn-cache

Any help you can offer would be great!

When I run ls node_modules I do see the symlink setup and the node_modules do exist!

Thanks again

./scripts/build.sh

#1/bin/bash

cd "$(dirname "../")"
pwd
touch yarn.lock

# Init empty cache file
if [ ! -f .yarn-cache.tgz ]; then
  echo "Init empty .yarn-cache.tgz"
  tar cvzf .yarn-cache.tgz --files-from /dev/null
fi

docker build . -t peterpme/testapp

docker run --rm --entrypoint cat peterpme/testapp:latest /tmp/yarn.lock > /tmp/yarn.lock
if ! diff -q yarn.lock /tmp/yarn.lock > /dev/null  2>&1; then
  echo "Saving Yarn cache"
  docker run --rm --entrypoint tar peterpme/testapp:latest czf - /root/.yarn-cache/ > .yarn-cache.tgz
  echo "Saving yarn.lock"
  cp /tmp/yarn.lock yarn.lock
fi
