拉取postgresql 18.0 docker镜像并运行容器

news 2025/9/27 8:54:22

postgresql 18.0今天发布了，在Linux上用容器来体验比较方便。
1.拉取镜像

docker pull docker.1ms.run/postgres:18

2.运行容器

用以往运行其他容器的方法来运行postgresql容器报错, 查看错误日志并把错误容器删除

root@DESKTOP-59T6U68:/mnt/c/Users/lt# docker run -it -d -v /mnt/c/d:/par --net=host --name pg18 docker.1ms.run/postgres:18
e1b81df353dbf810a75ba76b99a7486aec07eab3021368605b01c6e54b2ef6ff
root@DESKTOP-59T6U68:/mnt/c/Users/lt# docker exec -it pg18 bash
Error: can only create exec sessions on running containers: container state improper
root@DESKTOP-59T6U68:/mnt/c/Users/lt# docker logs --tail 10 pg18
Error: Database is uninitialized and superuser password is not specified.You must specify POSTGRES_PASSWORD to a non-empty value for thesuperuser. For example, "-e POSTGRES_PASSWORD=password" on "docker run".You may also use "POSTGRES_HOST_AUTH_METHOD=trust" to allow allconnections without a password. This is *not* recommended.See PostgreSQL documentation about "trust":https://www.postgresql.org/docs/current/auth-trust.html
root@DESKTOP-59T6U68:/mnt/c/Users/lt# docker container rm pg18

用网上看来的命令行，自己增加一些选项，还是报错

docker run -d \
--name pg18 \
-p 5432:5432 \
-e POSTGRES_PASSWORD=123456 \
-e POSTGRES_USER=postgres \
-e POSTGRES_DB=testdb \
-v /mnt/c/d:/par \
-v ~/postgresql/data:/var/lib/postgresql/data \--net=host \
docker.1ms.run/postgres:18
Port mappings have been discarded as one of the Host, Container, Pod, and None network modes are in use
Error: statfs /root/postgresql/data: no such file or directory

先建立-v选项中指定的宿主机目录，并将–net=host选项去掉，可以了

mkdir -p /root/postgresql/data
docker run -d \
--name pg18 \
-p 5432:5432 \
-e POSTGRES_PASSWORD=123456 \
-e POSTGRES_USER=postgres \
-e POSTGRES_DB=testdb \
-v /mnt/c/d:/par \
-v ~/postgresql/data:/var/lib/postgresql/data \
docker.1ms.run/postgres:18

也可以在宿主机上用psql登录容器中的数据库, 注意要指定-h选项

psql -U postgres -d testdb
