文件列表

-rw-r--r--. 1 root root 3962 Apr  8 17:13 docker-entrypoint.sh
-rw-r--r--. 1 root root 5649 Apr  8 17:13 Dockerfile

build成功后运行，报错：

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

 报错信息为 docker-entrypoint.sh 执行文件找不到，经过一番折腾，发现在build镜像时docker-entrypoint.sh没有执行权限。

解决办法：

1、更改文件权限

# chmod +x docker-entrypoint.sh

2、重新build镜像

# docker build -t postgres:10.3

3、运行容器

# docker run postgres:10.3

运行成功

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".

Data page checksums are disabled.

Success. You can now start the database server using:
