Make modifications to the container

We run a container and enter it, and customize it (install and modify)

[root@srv00 ~] # docker run-it centos [root@8a15586148ee /] # cat / etc/yum.repos.d/nginx.repo > [nginx] > name=nginx repo > baseurl= http://nginx.org/packages/centos/7/\$basearch/ > gpgcheck=0 > enabled=1 > EOF [root@8a15586148ee /] # yum install-y nginx [root@8a15586148ee /] # exit

Save the changes to the container. Kind of like git commit.

[root@srv00 ~] # docker ps-aCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES8a15586148ee centos "/ bin/bash" 21 minutes ago Exited (0) About a minute ago naughty_ dubinsky [root @ srv00 ~] # Docker commit-m "install nginx"-a "hippo" 8a15586148ee hippo/nginx:v1.10sha256:1e20546f8434d72cb350ae2081fc77690bdc599dbd984b5cdec09a7868013042

Give it a try.

[root@srv00] # docker run-d-p 80 hippo/nginx:v1.10 nginx-g "daemon off "616d942216ee7050ecff07ca66d2d7583d4093820e9d1448f96b417d7d779408 [root@srv00 ~] # docker ps-aCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES616d942216ee hippo/nginx:v1.10" nginx-g'daemon off "4 seconds ago Up 2 seconds 0.0.0.0 docker ps 32770-> 80/tcp high _ shockley [root@srv00 ~] # curl-L localhost:32770Welcome to nginxcake.

-d runs in the background, and-p maps the container port to the host. You can see through docker ps that it is mapped to 32770. Commands running in the nginx-g daemon off; container need to be run in the foreground. Otherwise, after starting the container, it will exit immediately.
