我们可以看到根目录中的空间已填满,所以我想将docker安装目录挂载到/ mnt.许多人建议包含-g选项,但我无法提供该选项.
谁能帮助我如何挂载到/ mnt目录以及在哪里进行这些更改.我正在使用centos 7,我已经在下面链接的帮助下安装了docker,我按照完全相同的步骤,
https://docs.docker.com/engine/installation/linux/centos/
并按照此处提供的步骤https://forums.docker.com/t/how-do-i-change-the-docker-image-installation-directory/1169进行操作
我无法在/ etc / sysconfig或/ etc / default中找到docker文件.请建议在哪里更改
Centos 7使用systemd,因此您可以在/etc/systemd/system/docker.service.d/override.conf中创建一个覆盖文件,该文件指定在启动时传递给dockerd的备用命令标志,以便使用/ var以外的目录/ lib / docker用于容器存储：
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd --graph=/mnt/docker-data --storage-driver=overlay
另一种选择是直接在/ var / lib / docker上挂载/ mnt处安装的磁盘.
进一步的细节在official docs.
