1. Download nginx
Docker pull nginx
two。 Start nginx
Docker run-d-m 2g-p 8888purl 80-- name lyjng nginx
3. Configure Mappin

Where:
Www: the directory will be mapped to the virtual directory configured by the nginx container.
Logs: the directory will map to the log directory of the nginx container.
Conf: the configuration file in the directory will be mapped to the configuration file of the nginx container.
4. Copy files in a docker container
[root@ambari-01 lyjnginx] # docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMEScf7da4042664 nginx "/ docker-entrypoint." 20 minutes ago Up 20 minutes 0.0.0.0 80/tcp 8888-> 80/tcp lyjng [root @ ambari-01 lyjnginx] # docker cp cf7da4042664:/etc/nginx/nginx.conf / root/lyjnginx/nginx/conf/
5. Deployment command
Docker run-m 2g-- rm-d-p 8889 root/lyjnginx/nginx/www:/usr/share/nginx/html 80-- name nginx-test-web-v / root/lyjnginx/nginx/www:/usr/share/nginx/html-v / root/lyjnginx/nginx/conf/nginx.conf:/etc/nginx/nginx.conf-v / root/lyjnginx/nginx/logs:/var/log/nginx nginx
Command description:
-m: set the container to occupy memory
-- rm: automatically delete container files when the container is terminated.
-p 8889 rig 80: map port 80 of the container to port 8889 of the host.
-- name nginx-test-web: name the container nginx-test-web
-v / root/lyjnginx/nginx/www:/usr/share/nginx/html: Mount the www directory we created to the container's / usr/share/nginx/html.
-v / root/lyjnginx/nginx/conf/nginx.conf:/etc/nginx/nginx.conf: Mount the nginx.conf we created to the / etc/nginx/nginx.conf of the container.
-v / root/lyjnginx/nginx/logs:/var/log/nginx: Mount the logs we created to the / var/log/nginx of the container.
6. Configure nginx.conf and restart the docker nginx container by modifying the / root/lyjnginx/nginx/conf/nginx.conf file.
