Docker 之 基本安装配置

一、安装epel源

yum install epel-release -y

二、添加docker源

yum install -y yum-utils yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

三、查看当前docer安装版本号

yum list docker-ce --show-duplicates

四、安装社区版docker

yum -y install docker-ce

五、创建配置docker的配置文件

docker]# vi /etc/docker/daemon.json { "graph": "/data/docker", "storage-driver": "overlay2", "insecure-registries": ["registry.access.redhat.com","quay.io"], "registry-mirrors": ["https://q2gr04ke.mirror.aliyuncs.com"], "bip": "172.7.5.1/24", "exec-opts": ["native.cgroupdriver=systemd"], "live-restore": true } graph: docker 工作目录 sotrage-dirver: docer存储驱动模式 insecure-registries:容器仓库 registry-mirrors:仓库加速镜像 bip:容器运行的网络 exec-opts:容器的启动方式 live-restore:当容器引擎中断时，所启动的容器继续运行 

六、启动&关闭&重启docker

启动: systemctl start docker 关闭: systemctl stop docker 重启: systemctl restart docker

七、查看当前容器信息

[root@docker docker]# docker info Client: Debug Mode: false Server: Containers: 0 Running: 0 Paused: 0 Stopped: 0 Images: 0 Server Version: 19.03.5 Storage Driver: overlay2 Backing Filesystem: extfs Supports d_type: true Native Overlay Diff: true Logging Driver: json-file Cgroup Driver: systemd Plugins: Volume: local Network: bridge host ipvlan macvlan null overlay Log: awslogs fluentd gcplogs gelf journald json-file local logentries splunk syslog Swarm: inactive Runtimes: runc Default Runtime: runc Init Binary: docker-init containerd version: b34a5c8af56e510852c35414db4c1f4fa6172339 runc version: 3e425f80a8c931f88e6d94a8c831b9d5aa481657 init version: fec3683 Security Options: seccomp Profile: default Kernel Version: 3.10.0-693.el7.x86_64 Operating System: CentOS Linux 7 (Core) OSType: linux Architecture: x86_64 CPUs: 1 Total Memory: 1.797GiB Name: docker ID: 2Q52:PFL3:RWZM:T77G:LAAB:NHX5:FWAL:4NDC:N6Q4:SNBU:BKRX:YWPW Docker Root Dir: /app/docker Debug Mode: false Registry: https://index.docker.io/v1/ Labels: Experimental: false Insecure Registries: quay.io registry.access.redhat.com 127.0.0.0/8 Registry Mirrors: https://q2gr04ke.mirror.aliyuncs.com/ Live Restore Enabled: true WARNING: bridge-nf-call-iptables is disabled WARNING: bridge-nf-call-ip6tables is disabled
