添加daemon.json文件后码头启动失败
提问于 2020-01-07 07:08:01
我正试图在CentOS 7.7上安装Kubernetes，因此，我必须先安装docker。我跟随Kubernetes文件安装docker并修改daemon.json文件。
$ yum install yum-utils device-mapper-persistent-data lvm2
$ yum-config-manager --add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
$ yum update && yum install \
containerd.io-1.2.10 \
docker-ce-19.03.4 \
docker-ce-cli-19.03.4
$ mkdir /etc/docker
$ cat > /etc/docker/daemon.json <<EOF
{
"exec-opts": ["native.cgroupdriver=systemd"],
"log-driver": "json-file",
"log-opts": {
"max-size": "100m"
},

"storage-opts": [
"overlay2.override_kernel_check=true"
]
}
EOF
$ mkdir -p /etc/systemd/system/docker.service.d
$ systemctl daemon-reload
$ systemctl start docker当启动码头服务时，它说：

Jan 07 15:28:25 love61y2223c.mylabserver.com systemd[1]: docker.service failed.有人能告诉我为什么码头服务启动后修改后daemon.json文件失败吗？以及如何正确地指定cgroupdriver、默认log-driver和默认storage-driver？
任何建议都将不胜感激。谢谢。

此错误指向一个问题，迫使停靠程序在没有适当备份文件系统的情况下使用overlay2：
failed to start daemon: error initializing graphdriver: overlay2: the backing xfs filesystem is formatted without d_type有关支持不同存储驱动程序的文件系统需求的详细信息，请参阅docker的表：https://docs.docker.com/storage/storagedriver/#supported-backing-filesystems
修复方法是删除存储驱动程序设置，或者用支持overlay2的所需选项修复备份文件系统：
{
"exec-opts": ["native.cgroupdriver=systemd"],
"log-driver": "json-file",
"log-opts": {
"max-size": "100m"
}
}有关更改xfs选项的详细信息，这似乎需要重新构建文件系统。有关所需步骤的更多详细信息，请参见这个答案。
