docker安装部署
1. 如何安装 Epel源到 RHEL/CentOS 7/6/5?
RHEL/CentOS 7 rpm -ivh http://mirrors.ustc.edu.cn/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm RHEL/CentOS 6 ## RHEL/CentOS 6 # wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm # rpm -ivh epel-release-6.noarch.rpm 如何检查epel是否安装成功? 使用一下命令: # yum repolist [root@17-150 ~]# yum repolist 已加载插件:fastestmirror base | 3.6 kB 00:00:00 epel/x86_64/metalink | 5.6 kB 00:00:00 epel | 4.3 kB 00:00:00 extras | 3.4 kB 00:00:00 updates | 3.4 kB 00:00:00 (1/5): extras/7/x86_64/primary_db | 191 kB 00:00:00 (2/5): epel/x86_64/group_gz | 170 kB 00:00:00 (3/5): epel/x86_64/updateinfo | 807 kB 00:00:01 (4/5): updates/7/x86_64/primary_db | 7.8 MB 00:00:04 (5/5): epel/x86_64/primary_db | 4.7 MB 00:01:05 Determining fastest mirrors * base: centos.ustc.edu.cn * epel: mirrors.ustc.edu.cn * extras: mirrors.sohu.com * updates: mirrors.sohu.com 源标识 源名称 状态 base/7/x86_64 CentOS-7 - Base 9,363 epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 11,769 extras/7/x86_64 CentOS-7 - Extras 449 updates/7/x86_64 CentOS-7 - Updates 2,146 repolist: 23,727
2. 安装docker-io
yum -y install docker-io yum install docker-engine
3. 启动docker服务
/etc/init.d/docker start
Starting cgconfig service: [ OK ]
Starting docker: [ OK ]
chkconfig docker on #设置docker服务开机启动
4. docker命令补全
安装docker自带包:
缺少下面的包,TAB会报错
yum install -y bash-completion sh /usr/share/bash-completion/bash_completion 或者执行 source /usr/share/bash-completion/completions/docker
显然,该脚本是用于bash自动补全的,但是,不幸的是,直接 source 执行该脚本后,docker命令后敲tab,有如下错误:
docker -bash: _get_comp_words_by_ref: command not found -bash: [: 1: unary operator expected -bash: [: 1: unary operator expected -bash: [: -eq: unary operator expected -bash: _get_comp_words_by_ref: command not found -bash: [: 1: unary operator expected -bash: [: 1: unary operator expected -bash: [: -eq: unary operator expected
难道docker的bash自动补全还能有问题?
解决办法如下:
我这里虽然安装了bash-completion ,但是没有执行其中的一个文件:
/usr/share/bash-completion/bash_completion
该文件中有上面缺少的命令,执行该文件,重新开一个shell终端 就解决了。
5. 如何使用docker加速器
安装/升级你的Docker客户端
推荐安装1.10.0以上版本的Docker客户端。
您可以通过阿里云的镜像仓库下载:docker-engine、docker-ce
或执行以下命令:
curl -sSL http://acs-public-mirror.oss-cn-hangzhou.aliyuncs.com/docker-engine/internet | sh -
针对Docker客户端版本大于1.10的用户
您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器:
sudo mkdir -p /etc/docker sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://sv1txjq6.mirror.aliyuncs.com"] } EOF sudo systemctl daemon-reload sudo systemctl restart docker
