k8s 之docker环境部署 (三)
1.在node 21上安装docker
[root@hdss7-21 ~]# curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
[root@hdss7-21 ~]# mkdir -p /data/docker
[root@hdss7-21 ~]# mkdir -p /etc/docker
[root@hdss7-21 ~]# vim /etc/docker/daemon.json
[root@hdss7-21 ~]# cat /etc/docker/daemon.json
{
"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
}
[root@hdss7-21 ~]# systemctl start docker
[root@hdss7-21 ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
[root@hdss7-21 ~]# docker info
2.在node22上安装docker
[root@hdss7-22 ~]# curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
[root@hdss7-22 ~]# mkdir -p /etc/docker
[root@hdss7-22 ~]# mkdir -p /data/docker
[root@hdss7-22 ~]# vim /etc/docker/daemon.json
[root@hdss7-22 ~]# cat /etc/docker/daemon.json
{
"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": "172.7.22.1/24",
"exec-opts": ["native.cgroupdriver=systemd"],
"live-restore": true
}
[root@hdss7-22 ~]# systemctl start docker
[root@hdss7-22 ~]# systemctl enable docker
3.在node200上安装docker
[root@hdss7-200 ~]# curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
root@hdss7-200 ~]# mkdir -p /etc/docker
[root@hdss7-200 ~]# mkdir -p /data/docker
[root@hdss7-200 ~]# vim /etc/docker/daemon.json
[root@hdss7-200 ~]#
[root@hdss7-200 ~]#
[root@hdss7-200 ~]#
[root@hdss7-200 ~]# cat /etc/docker/daemon.json
{
"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": "172.7.200.1/24", # 定义k8s主机上k8s pod的ip地址网段 -- 改成node节点的ip
"exec-opts": ["native.cgroupdriver=systemd"],
"live-restore": true
}
[root@hdss7-200 ~]# systemctl start docker
[root@hdss7-200 ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
