二进制部署K8S集群（四）前置准备工作之docker环境安装 ​


0.架构图


1.本节架构

主机

IP

角色

hdss-7-21.host.com

10.4.7.21

docker

hdss-7-22.host.com

10.4.7.22

docker

hdss-7-200.host.com

10.4.7.200

docker

2.安装

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun


3.配置docker

mkdir -p /etc/docker /data/docker
cat > /etc/docker/daemon.json <<'eof'
{ 
  "graph": "/data/docker",
  "storage-driver": "overlay2",
  "insecure-registries": ["registry.access.redhat.com","quay.io","harbor.od.com"],
  "registry-mirrors": ["https://q2gr04ke.mirror.aliyuncs.com"], 
  "bip": "172.7.21.1/24",
  "exec-opts": ["native.cgroupdriver=systemd"],
  "live-restore": true
}
eof


不同地方："bip"："172.7.21.1/24"，分别在各自主机配置为当前主机IP最后一位

如：hdss-7-200.host.com配置为"bip"："172.7.200.1/24"

hdss-7-21.host.com配置为"bip"："172.7.21.1/24"

hdss-7-22.host.com配置为"bip"："172.7.22.1/24"

4.启动验证docker

systemctl start docker
systemctl enable docker.service
docker info 
docker version
docker ps -a
