1. List the mirror list: docker images
2. Get a new mirror: docker pull ubuntu: 13.10
3. Find Mirror: docker search httpd
4. Mirror pulling them: docker pull httpd
5. Mirror: docker run httpd
6. Remove Mirror: docker rmi httpd
7. Set mirror Tags: docker tag <containers ID> test / centos: dev
8. Create image:
(1) update image has been created from container and submit this image
. A mirror used to create a container: docker run -t -i ubuntu: 15.10 / bin / bash
b. Make apt-get update using the update command within the operating container.
c. Enter the exit command to exit the container
. D container to submit a copy of the command docker commit: docker commit -m = "has update" -a = "tester" <container id> test / ubuntu: v2
Various parameters:
-m: description of the information submitted
-a: Specifies the mirroring of
test / ubuntu: v2: Specifies the name of the target image to be created
. E view the new image runoob / ubuntu: v2: docker images
(2) instructions to use Dockerfile create a new image
. A Dockerfile create a file, the file contents are as follows:
FROM centos:6.7
MAINTAINER Fisher "[email protected]"
RUN /bin/echo 'root:123456' |chpasswd
RUN useradd test
RUN /bin/echo 'test:123456' |chpasswd
RUN /bin/echo -e "LANG=\"en_US.UTF-8\"" >/etc/default/local
EXPOSE 22
EXPOSE 80
CMD /usr/sbin/sshd -D
Each command will create a new layer on the mirror, prefix each command must be capitalized.
The first FROM, which mirror source specify
RUN command tells docker execute commands in the mirror, what is installed
b constructed by a mirror docker build command:. docker build -t test / centos: 6.7
Parameter Description:
-t: Specifies the name of the target image to be created
.: Dockerfile file directory, you can specify the absolute path Dockerfile
c view mirror created:. docker images (should the new mirrors already exists)
. D used to create a new image container: docker run -t -i test / centos: 6.7 / bin / bash
. E enter into the container: id test (new image has been created that contains the user test us)
