How docker starts image

Method 1: Execute docker run command to start

For example:

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

Parameter introduction:

–env-file means to load environment variables from a file. The file format is key=value, one variable per line.

-v means to mount the file on the host into the image. The colon in front of it means the host file path. The latter represents the image file path, and the absolute path

-p represents mapping the 8080 port in the image to the 8083 port on the host. 10.142.8.12 represents the host ip
