After creating a container locally, you can create a local image based on the container, and push the image to Docker hub for download and use on the network.

Let's put it into practice.

Docker pull nginx:1.15.3

Start a container with the command line:

Docker run-d-p 1080 docker run-- name jerry-nginx nginx:1.15.3

Localhost:1080

Enter the shell of the container:

Docker exec-it jerry-nginx / bin/bash

Check the default home page of this nginx image:

I want to use wget in the container, so install it first:

Apt-get update & & apt-get-y install wget

Use the wget command to download an image file and a html file to the location of the Nginx server where the web page is stored:

Wget-- no-check-certificate-O / usr/share/nginx/html/evil.jpg https://github.com/raw/slvi/docker-k8s-training/master/docker/res/evil.jpgwget-- no-check-certificate-O / usr/share/nginx/html/index.html https://github.com/raw/slvi/docker-k8s-training/master/docker/res/evil.html

Refresh the page, and the page we see now has become the page downloaded by wget:

We now want to solidify the changes found in this container so that others can use it.

Docker commit jerry-nginx jerry-modify-nginx:1.0

Sha256:7e243a7b4c0796e3a787fe963224fdf1fe81d9fe9b283f6f3e4f17e1defa0c96

Use the command to set 1.0 to latest tag:

Docker tag jerry-modify-nginx:1.0 jerry-modify-nginx:latest

Stop the old container with docker stop jerry-nginx, and then start the modified container jerry-modify-nginx:

Docker history name to view the history of this new image:

Execute the command to label the new image:

Docker tag jerry-modify-nginx:latest registry.ingress.shcw46.k8s-train.shoot.canary.k8s-hana.ondemand.com/jerry-modify-nginx:760d7ca6

Push the tagged image to the remote end:

Docker push registry.ingress.shcw46.k8s-train.shoot.canary.k8s-hana.ondemand.com/jerry-modify-nginx:760d7ca6
