容器來源於使用官方Dockerfile build的鏡像 https://github.com/docker-library/postgres/tree/master/10
環境：CentOS 7

build成功后運行，報錯：
docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"docker-entrypoint.sh\": executable file not found in $PATH": unknown. ERRO[0000] error waiting for container: context canceled
報錯信息為 docker-entrypoint.sh 執行文件找不到，經過一番折騰，發現在build鏡像時docker-entrypoint.sh沒有執行權限。
解決辦法：
1、更改文件權限
# chmod +x docker-entrypoint.sh
2、重新build鏡像
# docker build -t postgres:10.3
3、運行容器
# docker run postgres:10.3
運行成功
The files belonging to this database system will be owned by user "postgres". This user must also own the server process. The database cluster will be initialized with locale "en_US.utf8". The default database encoding has accordingly been set to "UTF8". The default text search configuration will be set to "english".
