Docker Common Commands

Modify the container, and then save the image to the local

$ sudo docker commit-m "Added json gem"-a "Docker Newbee" 0b2616b0e5a8 ouruser/sinatra:v2

Where-M to specify the description of the submission, as we use the version Control tool;-A can specify updated user information;

Is the ID of the container used to create the mirror, and finally specifies the warehouse name and tag information for the target image. The ID of this image is returned when the creation is successful

Information.

Docker directory:/var/lib/docker/

Download the image of the library from the public repository and start:

The image file can be stored locally by using the-v parameter.

Specifies the path. For example, the following example places the uploaded image into the/opt/data/registry directory.

$ sudo docker run-d-p 5000:5000-v/opt/data/registry:/tmp/registry Registry

#docker run-d-P 5000:5000--name my_registry-v/home/test/registry:/tmp/registry index.alauda.cn/library/registry

To enter into the container operation:

Docker exec-it Centos_test1/bin/bash

When uploading images from a library to a library, both the library and the remote machine need to modify the Docker boot parameters:

Ubuntu14.0

Vim/etc/default/docker

Add the following line

docker_opts= "$DOCKER _opts--insecure-registry=104.131.173.242:5000"

Restart Docker

sudo service docker restart

#修改docker文件 (centos6.5 version)

Root > Vim/etc/sysconfig/docker

other_args= "--insecure-registry www.monicacca.com:5000"

Docker_cert_path=/etc/docker

#重启docker

Root>sudo Service Docker Restart

Before entering the library, you need to change the image to the tag identified by the library:

[Email protected]:/home/test# docker tag csphere/centos_snap:7.1 10.1.1.156:5000/csphere/centos_snap:7.1

Passing an image into a private library

Docker Push 10.1.1.156:5000/csphere/centos_snap

To view the library:

Curl Http://10.1.1.156:5000/v1/search

Create a data container to share the same data storage directory with other containers, and the data container does not need to be run:

# docker run-d-v/dbdata--name dbdata csphere/centos:7.1 echo "Data-only container"

#docker run-d--volumes-from dbdata--name centos_db1 csphere/centos:7.1

Docker run-d--volumes-from dbdata--name centos_db2 csphere/centos:7.1

To view the logs for a container:

#docker logs-f CENTOS_DB1

Container interconnection:

#docker run-d--name db1 csphere/mysql:5.5

#docker run-d-P--name web2--link db1:db1 csphere/php-fpm:5.4 (previous DB1 is the database container name, followed by an alias)

#docker exec-it Web2/bin/bash

Multiple web containers can link to a DB container

After the Mount host already exists the directory, in the container to operate it, reported "Permission denied".

There are two ways to solve this:

1> off SELinux.

Temporary close: # Setenforce 0

Permanently closed: Modify the/etc/sysconfig/selinux file to set the SELinux value to disabled.

2> to start a container in a privileged manner

Specifying the--privileged parameter

such as: # Docker run-it--privileged-v/test:/soft Centos/bin/bash
