How to deploy nginx in the docker container, many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can get something.

1. Find Mirror

Docker search nginx

two。 Pull the official Nginx image

Docker pull nginx

3. Create a local data volume:

Mkdir-p / home/nginx/www / home/nginx/logs / home/nginx/conf

4. Add host directory permissions

Chmod-R 777 / home/nginx/www

5. The default profile starts the nginx container:

Docker run-- rm-- name nginx-test-p 80:80-d nginx

6. Copy the configuration file to the local directory:

Docker cp Container id:/etc/nginx/nginx.conf / home/nginx/conf

7. Enter the container:

Docker container exec-it container id / bin/sh

8. Start the nginx container to mount the host directory and map the port

Docker run-d-p 80:80-- name nginx-test-web\

-v / home/nginx/www:/usr/share/nginx/html\

-v / home/nginx/conf/nginx.conf:/etc/nginx/nginx.conf\

-v / home/nginx/logs:/var/log/nginx\

-- privileged=true nginx:1.15.7-alpine

Image recovery and migration

1. The container is saved as a mirror

Docker commit Container name Image name

two。 Mirror backup

Docker save-o mynginx.tar mynginx

3. Upload and import images

Upload: rz

Download: sz file name

Docker load-I mynginx.tar

Other common docker commands:

Delete container: docker rm container id

Delete image: docker rmi image id

Install tree:yum-y install tree

View directory: tree directory name.

Docker run is used only the first time it is run, putting the image in a container, and when you start the container again later, you only need to use the command docker start.

Docker run is equivalent to two steps: put the image in the container (docker create), and then launch the container to make it a run-time container (docker start).

The purpose of docker start is to restart an existing mirror. That is, if we use this command, we must know the ID of the container, or the name of the container, and we can use docker ps to find the information about the container.
