报错信息:
harbor-db容器重启报错:initdb: error: directory “/var/lib/postgresql/data/pg13“ exists but is not empty
现象:
在重启docker服务或者通过docker-compose重启harbor服务时,harbor-db容器都一直处于Restarting状态,无法恢复UP状态。

Harbor版本:v2.3.2

1.查看harbor所有容器启动日志路径

2.查看harbor-db容器启动日志

解决:
1.从上面日志中的提示directory "/var/lib/postgresql/data/pg13" exists but is not empty可以清楚/var/lib/postgresql/data/pg13这个目录存在,并且不为空,但是在宿主机上找不到这个目录。
[root@k8s-master harbor]# ll /var/lib/postgresql/data/pg13ls: 无法访问/var/lib/postgresql/data/pg13: 没有那个文件或目录
复制
2.于是想到查看一下docker-compose的yaml文件,查看一下harbor-db容器的挂载目录的信息。
[root@k8s-master harbor]# vim docker-compose.yml...postgresql: image: goharbor/harbor-db:v2.3.2 container_name: harbor-db restart: always cap_drop: - ALL cap_add: - CHOWN - DAC_OVERRIDE - SETGID - SETUID volumes: - /home/harbor/data/database:/var/lib/postgresql/data:z //挂载目录信息 networks: harbor: dns_search: . env_file: - ./common/config/db/env depends_on: - log logging: driver: "syslog" options: syslog-address: "tcp://127.0.0.1:1514" tag: "postgresql"...
复制
3.从docker-compose.yaml文件中可以看到宿主机上的/home/harbor/data/database目录挂载到容器中的/var/lib/postgresql/data目录下,那会不会是/home/harbor/data/database目录不为空呢?删除掉它试试。
[root@k8s-master harbor]# rm -rf /home/harbor/data/database
复制
4.删除/home/harbor/data/database目录后将harbor运行的容器删除,在重新创建并启动。
[root@k8s-master harbor]# docker-compose down -vStopping harbor-jobservice ... doneStopping nginx ... doneStopping harbor-core ... doneStopping redis ... doneStopping harbor-portal ... doneStopping harbor-db ... doneStopping registry ... doneStopping registryctl ... doneStopping harbor-log ... doneRemoving harbor-jobservice ... doneRemoving nginx ... doneRemoving harbor-core ... doneRemoving redis ... doneRemoving harbor-portal ... doneRemoving harbor-db ... doneRemoving registry ... doneRemoving registryctl ... doneRemoving harbor-log ... doneRemoving network harbor_harbor[root@k8s-master harbor]# docker-compose up -dCreating nginx ... doneCreating registryctl ...Creating registry ...Creating harbor-db ...Creating redis ...Creating harbor-portal ...Creating harbor-core ...Creating harbor-jobservice ...Creating nginx ...[root@k8s-master harbor]# docker-compose ps Name Command State Ports--------------------------------------------------------------------------------------harbor-core /harbor/entrypoint.sh Upharbor-db /docker-entrypoint.sh Upharbor-jobservice /harbor/entrypoint.sh Upharbor-log /bin/sh -c /usr/local/bin/ ...

复制
可以看到harbor-db已经启动成功,恢复正常了。
原因:
1.出现如上的原因很大可能是之前在这台机器上安装过Harbor服务,第一次安装的时候在挂载目录下创建了数据,再次安装时需要将之前的脏数据都清空才可以;
2.还遇到过一种情况,那就是在清理了挂载目录的脏数据之后重启docker服务或者使用docker-compose重启Harbor服务时,harbor-db容器还是一直处于Restarting状态,这种情况下可以将Harbor所有容器都down -v删除掉,修改harbor.yaml中data_volume数据挂载目录,再重新up -d(成功过)。或者换一个Harbor的版本,实测Harbor v2.1.1版本可以(之前是Harbor v2.3.2)。
