Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xeu docker.service" for details.、Job for docker.service failed because the control process exited with error code、systemctl status docker.service" and "journalctl -xeu docker.service

实现步骤

1. 启动docker报错

root@primary:/service/java/docker# systemctl start docker.service
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xeu docker.service" for details.

1.1 systemctl status docker.service查看docker服务的状态

• 使用docker时，遇到 docker.service的作业失败，因为控制进程已退出，并返回错误代码。
• 有关详细信息，请参阅“systemctl status docker.service”和“journalctl -xe”时，不一定要重装 docker。

systemctl status docker.service

1.2 journalctl -xe 查看报错信息

root@primary:/etc/docker# journalctl -xe

分析错误： No space left on devic> 设备上没有剩余空间，在错误日志中我们发现是docker安装目录满了。

解决方案：

1. 查看目录下剩余空间

df -hl /var/lib/docker
# 显示的信息：使用已经百分百
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1       4.7G  4.7G     0 100% /

2. 查看分区容量

df -h
# 显示的信息
Filesystem      Size  Used Avail Use% Mounted on
tmpfs            97M   11M   86M  12% /run
/dev/sda1       4.7G  4.7G     0 100% /
tmpfs           482M     0  482M   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
/dev/sda15       98M  6.3M   92M   7% /boot/efi
tmpfs            97M  4.0K   97M   1% /run/user/1000

3. 知道是磁盘不足，由于我们现在docker启动不了，星辰推荐先扩容，后面在对容器和镜像进行优化。

我是在Mac虚拟机（multipass）上运行的docker，默认磁盘5G，所以我们调整一下磁盘大小就可以，下面有我找到的一个博主的参考。

# 打开终端
xingchen@star-2 ~ % multipass ls
Name                    State             IPv4             Image
primary                 Stopped           --               Ubuntu 22.04 LTS

# 扩容命令,等号左右不能有空格
# 要修改其中一个属性，请先停止实例，然后发出命令set。例如：
multipass set local.primary.disk=10G

xingchen@star-2 ~ % multipass set local.primary.disk=10G
xingchen@star-2 ~ % 
# 可以使用命令查询这些属性get。不必为此停止实例。例如：
multipass get local.primary.disk


# 扩容完毕我们启动虚拟机在查看容量
df -h
root@primary:/home/ubuntu# df -h
# 显示的信息
Filesystem      Size  Used Avail Use% Mounted on
tmpfs            97M   11M   86M  12% /run
/dev/sda1       4.7G  4.7G     0 100% /
tmpfs           482M     0  482M   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
/dev/sda15       98M  6.3M   92M   7% /boot/efi
tmpfs            97M  4.0K   97M   1% /run/user/1000

# 发现一个问题，multipass 扩容以后系统磁盘不变
# 扩展完磁盘后使用lsblk查看的结果变了而使用df -h结果大小却没变，这是因为前者查看的是磁盘的大小而后者查看的是文件系统的大小。磁盘和文件系统在不严格区分时可视为同一个东西，但追究起来确实是两样东西。
