Notes for docker

  • Not using everyday so need instructions on how I use it
  • Removing Docker containers and images
  • Reset containers when using docker-compose. docker-compose up --force-recreate
  • Reset everything - docker-compose down --remove-orphans -v --rmi all
  • ElasticSearch

Starting and using

  • Now using Docker for Mac
  • docker-machine start default
  • Set the environment
    • Configure Shell (Docker Toolbox on Mac)
      • eval "$(docker-machine env default)"
  • docker-machine config - verify can connect and pull info from the machine

Use a base alpine image for docker

Nginx docker config

  • sudo docker cp docker-nginx:/etc/nginx/conf.d/default.conf default.conf - Copy config file from docker container

Setup nginx-unit with docker

  • yousan/nginx-unit - instructions on getting access to the socket.
  • Nginx Unit Integration
  • docker-compose.yml

Setup nginx-unit with docker

  • Using Docker for Mac
  • Using docker-compose.yml
      nginx-unit:
        image: "nginx/unit:1.1-full"
        container_name: nginx-unit
        ports:
          - 8081:8081
          - 8200:8200
          - 8300:8300
        volumes:
          - ../containers/nginx/json:/root/json
          - ../containers/nginx/www/root:/www/root
    
  • Create index.php in ./containers/nginx/html
  • json.local in ./containers/nginx/json
    {
        "listeners": {
                "*:8300": {
                        "application": "blogs"
                }
        },
    
        "applications": {
                "blogs": {
                        "type": "php",
                        "processes": 20,
                        "root": "/www/root",
                        "index": "index.php"
                }
        }
    }
    

Creating the setup

  • Create configuration in docker-compose.yml file
  • Copy json.local to containers/nginx/json
  • Copy index.php to containers/nginx/www/root
  • docker-compose up -d - start the containers
  • docker-compose exec nginx-unit curl -X PUT -d @/root/json/local.json --unix-socket /var/run/control.unit.sock http://localhost/ - set the configuration for nginx unit
  • Access the file at http://localhost:8300

Errors

  • ERROR: network lookfindmeapi_default id ae6c919c63c2f8a9ed5a5aea2ba716f4b19efe4fd7599fc0262a991d6e34b494 has active endpoints
    • docker-compose ps
    • docker stop {container}
    • docker container prune
