CentOS Docker 安装 Docker 支持以下的 64 位 CentOS 版本： CentOS 7 CentOS 8 更高版本. 使用官方安装脚本自动安装 安装命令如下： curl -fsSL bash -s docker -mirror Aliyun 也可以使用国内 daocloud 一键安装命令： curl -sSL https://get.daoclou. How can I setup Docker on a CentOS 7? How to install and use Docker CE on a CentOS Linux 7 server? Docker is free and open-source software. It automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually anywhere. Typically you develop software on your laptop/desktop. $ docker commit 4f0b435cdbd7 man-centos $ docker run -i -t man-centos root@953c512d6707 /# man man No manual entry for man. Now we have a CentOS container where man is already installed. I can't (that I know of) inspect the container and know whether or not man is installed without running it. Docker installation on CentOS 7 is a bit easier than installing on Ubuntu. If you followed this guide, you should have successfully installed Docker on your CentOS 7 machine. Now you can explore the wonderful world of Docker.
Docker is a popular application containment environment on GNU/Linux that is available on FreeBSD as of June, 2015. Docker on FreeBSD relies heavily on ZFS, jail and the 64bit Linux compatibility layer that was introduced in June, 2015. Docker on FreeBSD is genuine Docker and retrieves containers from the official docker.io repository. Consult the official Docker documentation and resources for further assistance.
Status
Docker's currently broken. We are working on a current, executable version. Help is welcome. Current status: https://reviews.freebsd.org/D21570
Limitations of the 64bit Linux compatibility subsystem will impact some Linux ABI containers and your testing and feedback is appreciated to help resolve any such issues.
The freebsd-virtualization mailing list, as well as the IRC channels #freebsd-docker and #bhyve on chat.freenode.net are good places to participate.
Docker Centos Run
Requirements
FreeBSD 11.1-RELEASE or newer, specifically any version after preliminary support for x86-64 Linux binaries was addded.
Repository
github.com/kvasdopil/docker contains the port of Docker for FreeBSD.
sysutils/docker-freebsd contains the FreeBSD port for Docker. Docker port.
Installation and Use
Cleanmymac full version. The following steps, executed with root privileges, should provide a working Docker environment:
If you're not already using ZFS, you will need to create a raw disk, otherwise follow the above steps as instructed in the package message.
Using Docker as a normal user
In order to use Docker as a non-root/non-super user account, your user must be in the operator group:
After changing your user's group membership, log out and back in. Once logged back in docker ps should be usable (for example) as a non-superuser.
From another terminal:
Creation of a ZFS root using raw disk
These steps are only necessary if you're not already using ZFS.
The following steps allocate a 4G ZFS root file system using a raw disk, it allows you to test quickly.
FreeBSD under Docker
Networking
Common Errors
The 'docker' dataset needs to be created.
The 'ca_root_nss' package is not installed.

CategoryHowTo
I'm just getting started with Docker. I've thought for years that containerization is a great idea, but I haven't actually done anything with containers yet. Time to get started.
I ran through a couple tutorials on the Docker docs site and created a cloud.docker.com account to get some basic familiarity.
I found the CentOS container repository on Docker Hub: https://hub.docker.com/_/centos/
Let's try running it!
$ docker pull centos
$ docker run centos
Docker Run Centos 7 Image
Did it do anything? It looks like it did something. At least, it didn't give me an error. What did it do? How do I access it?
$ docker container ls
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
Nothing is actively running. That makes sense, because we're not telling the containerized OS to do anything — it starts, it doesn't have anything to do, and so it shuts down immediately. Instead we can tell it to run interactively and with a terminal by specifying a couple options:
-i, --interactive ('allocate a pseudo-TTY', i.e. a terminal)
-t, --tty
(see docker run --help for details)
$ docker run -i -t centos
[root@4f0b435cdbd7 /]#

$ docker run -i -t centos
[root@4f0b435cdbd7 /]#
I'm in!
Docker Centos Run Yum
What if I want to modify the container? Right now it is pretty bare-bones. For example, this doesn't even have man installed:
[root@4f0b435cdbd7 /]# man man
bash: man: command not found
Docker Centos Running
[root@4f0b435cdbd7 /]# yum install man
..
[root@4f0b435cdbd7 /]# man man
No manual entry for man
Quite the improvement! Now we need to save our change:
[root@4f0b435cdbd7 /]# exit
Docker Centos Run Httpd
$ docker commit 4f0b435cdbd7 man-centos
$ docker run -i -t man-centos
[root@953c512d6707 /]# man man
No manual entry for man
Progress! Now we have a CentOS container where man is already installed. Exciting.
I can't (that I know of) inspect the container and know whether or not man is installed without running it. That's fine for many cases, but next I will attempt to figure out how specify via a Dockerfile that man is installed.
