安装Docker之后,我已经将SELinux状态设置为 Permissive ,仍然不能运行Docker。

在我的 /etc/selinux/config ,我已经编辑了 SELINUX=disabled .

和 setenforce 0 ,检查:

# getenforce
Permissive

我使用 systemctl start docker ,但失败,获取以下错误:

# systemctl status docker.service

为什么还说:

启动守护程序时出错:覆盖图dr…false不支持selinux)

我找到了解决办法。

在 /etc/sysconfig/docker 以下内容:

OPTIONS='--selinux-enabled --log-driver=journald --signature-verification=false'
if [ -z "${DOCKER_CERT_PATH}" ]; then
    DOCKER_CERT_PATH=/etc/docker
fi

设置 -selinux-enabled 到 --selinux-enabled=false .
