場景
postgresql數據庫在docker環境安裝插件，修改配置（增加pglogical擴展加載）后無法啟動容器了
啟動時報錯
Error response from daemon: Container 130e4f7fc99d06d98a6d1542b16580ff25475b9cff892a75cde26743xxx676d3 is restarting, wait until the container is running
排查步驟
查看容器的錯誤日志
docker logs postgres
2020-05-06 06:17:12.624 UTC [1] FATAL: could not access file "pglogical": No such file or directory
2020-05-06 06:17:12.624 UTC [1] LOG: database system is shut down
如上報錯pglogical插件不存在（修改配置時增加了shared_preload_libraries = 'pglogical'導致）
解決
-
將配置文件復制出來
docker cp 730e4f7fc99d:/var/lib/postgresql/data/postgresql.conf postgresql.conf
修改去掉pglogical插件的預加載 -
將配置文件到容器中
docker cp postgresql.conf 730e4f7fc99d:/var/lib/postgresql/data/postgresql.conf
docker restart [容器ID] 就能重新啟動了
