Docker. Run Container.

Docker

I had a small task - run container with parameters:

  1. Name is web
  2. Image is nginx:latest
  3. The container must be available on port 9099
  4. The /var/log/nginx directory inside the container must be mounted to the /data/nginx/logs directory on the host system
  5. When starting the container, the environment variable logging = true should be added

Complete instruction for starting the container:

docker run -d --name web -p 9099:80 -v /data/nginx/logs:/var/log/nginx \
           -e logging=true nginx:latest

Explanation:

  • docker run - start container
  • -d - detached mode
  • –name web - set name
  • -p 9099:80 - port forwarding - 9099 is host’s port, 80 is container’s port
  • -v /data/nginx/logs:/var/log/nginx - mount directory, analog: --mount type=mount,src=/data/nginx/logs,dst=/var/log/nginx
  • -e logging=true - set environment variable
  • nginx:latest - nginx is image, latest is tag(sometimes version)
