How to start docker image

1. Docker run startup

--env-file means loading environment variables from a file. The file format is key=value, one per line. Variable;

-v means to mount the files on the host into the image. The front of the colon indicates the host file path, and the following indicates the image file path. Absolute paths must be used;

- p means mapping port 8080 in the image to port 8083 on the host, and 10.142.8.12 represents the host IP;

docker run -it --env-file ./run/hrms.env -v /opt/hrms/hrms/hrms:/opt/hrms/hrms -p 10.142.8.12:8083:8080 55ad68601db

2. Docker-compose startup

docker-compose is one of the three docker musketeers. It is a plug-in specifically used to start images. It can be installed through pip install docker-compose.

You can create a new folder with the following directory structure as the startup folder of the image:

Write the docker-compose.yml file:

version: '2.0' services: web: image: hrms:v1.2 restart: always ports: - "8083:8080" env_file: - ./hrms.env volumes: - /opt/hrms/logs/:/opt/hrms/logs/

Startup:

Switch to the directory where docker-compose.yml is located and execute:

docker-compose up

to start the image.
