ENOSPC: System limit for number of file watchers reached

Description of the bug

Basically a duplicate of https://github.com/expo/expo-cli/issues/277

To Reproduce

Run expo publish using default configuration in README, with slight modifications:

• use yarn instead of NPM
• use a release-channel option

I don’t believe these options may result in not being able to publish though.

name: Expo Review App
on:
  pull_request:
    types: [opened, synchronize, reopened]
jobs:
  publish:
    name: Install and publish
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v1
      - uses: actions/setup-node@v1
        with:
          node-version: 12.x
      - uses: expo/expo-github-action@v4
        with:
          expo-version: 3.x
          expo-username: ${{ secrets.EXPO_CLI_USERNAME }}
          expo-password: ${{ secrets.EXPO_CLI_PASSWORD }}
      - run: yarn install
      - run: expo publish --release-channel=pr-${{ github.event.number }}

Expected behavior

expo publish to succeed

Actual behavior

Following error in the expo publish ... step

ENOSPC: System limit for number of file watchers reached

Additional context

I’m curious, because you state that running expo publish is not working in the related issue, and that’s actually what I see too.

However you also seem to succeed publishing using this action and default configuration 🤷‍♂

So, there exists a fix, that seemed to work for me when I tried. What I did was to follow this guys tip: “Increasing the number of watchers” — @JNYBGR https://link.medium.com/9Zbt3B4pM0

I then did this in my main action.yml With all the specifics underneath the dev release

    steps:
    - uses: actions/checkout@v1
    - name: Setup kernel for react native, increase watchers
      run: echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
    - name: Run dev release fastlane inside docker action

I can confirm that I got past the watch step and was able to finish my dockerized fastlane build and release action

@vongohren It works indeed 🎉

Here is my complete configuration for reference:

on:
  push:
    branches:
      - master
jobs:
  publish:
    name: Install and publish
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v1
      - name: Setup kernel for react native, increase watchers
        run: echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
      - uses: actions/setup-node@v1
        with:
          node-version: 12.x
      - run: npm ci
      - uses: docker://bycedric/expo-cli-fix-inotify:latest
        with:
          args: publish
        env:
