Logging to stdout:

  > /dev/stdout
  

Increase php cli memory size for one command

  php -d
  

Dockerfile

Create non-root user. In this case we remove the node user and create a new one called application

  RUN userdel -r node \
 && useradd application --home-dir /home/application --uid 1000 \
 && mkdir -p /home/application /app \
 && chown application:application /home/application /app
  
  COPY --from build_stage --chown=application:application /build/out/ /app/
  

Install Packages and Remove Cache

  apt-get update \
 && apt-get install -y \
  abc \
  def \
 && rm -rf /var/lib/apt/lists/*
  

Limit a services memory / cpu usage

  services:
  stress:
    image: image
    deploy:
      replicas: 1
      resources:
        limits:
          cpus: '0.50'
          memory: 750M
  

Using webdevops

cronjob

  RUN docker-cronjob '* * * * * cd /path-to-your-project && php artisan schedule:run >> /dev/null 2>&1'
  

supervisor apps

Copy to /opt/docker/etc/supervisor.d/

Example:

  [group:hhvm]
programs=hhvmd
priority=20

[program:hhvmd]
command = /opt/docker/bin/service.d/hhvm.sh
process_name=%(program_name)s
directory = /var/run/hhvm/
startsecs = 0
autostart = true
autorestart = true
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0
  

Env file

If you need to do spaces, you must escape them

  APP_NAME=my\ app\ name
  

Tricks

Copy from docker image -> file: source

  docker run --rm --entrypoint cat yourimage  /path/to/file > path/to/destination
