安装docker-centos
安装docker
卸载旧版docker
yum remove docker \ docker-client \ docker-client-latest \ docker-common \ docker-latest \ docker-latest-logrotate \ docker-logrotate \ docker-engine
如果yum
报告未安装这些软件包,则可以。
配置docker的yum源
yum install -y yum-utils?yum-config-manager \ --add-repo \ https://download.docker.com/linux/centos/docker-ce.repo
机子自身配置好epel源以及阿里云的源
yum install docker-ce docker-ce-cli containerd.io -y?systemctl start docker?
验证:
docker run hello-world
输出:
Unable to find image ‘hello-world:latest‘ locally docker: Error response from daemon: Get https://registry-1.docker.io/v2/library/hello-world/manifests/latest: Get https://auth.docker.io/token?scope=repository%3Alibrary%2Fhello-world%3Apull&service=registry.docker.io: net/http: TLS handshake timeout. See ‘docker run --help‘.
证明你没有设置加速器。国内有限制
所以咱们就是去阿里云找一个属于自己的加速连接
mkdir -p /etc/docker ?tee /etc/docker/daemon.json <<-‘EOF‘ { "registry-mirrors": ["https://ka8o6acz.mirror.aliyuncs.com"]}EOF?systemctl daemon-reload ?systemctl restart docker?在来一次:docker run hello-world?
输出:
……Hello from Docker!……
证明成功了!
