This article mainly introduces "how to use the Docker image submission command commit". In the daily operation, I believe many people have doubts about how to use the Docker image submission command commit. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "how to use the Docker image submission command commit". Next, please follow the editor to study!

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

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

At this point, the study on "how to use the Docker image submission command commit" is over. I hope to be able to solve your doubts.
