安装docker postgres15

1. 运行这个命令：$ sudo docker pull postgres:15

Status: Downloaded newer image for postgres:15
docker.io/library/postgres:15

2. 创建数据+密码

运行这个命令：$ docker run -e POSTGRES_PASSWORD=abdfdd3859a24c -d postgres

docker run -e POSTGRES_PASSWORD=abdfdd3859a24c -d postgres

docker: permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/create": dial unix /var/run/docker.sock: connect: permission denied.
See 'docker run --help'.

会报错，使用 Docker 命令时遇到了权限问题。这是由于您在没有足够权限的情况下尝试执行 Docker 命令导致的。

在命令前面加上sudo，再重新运行：$ sudo docker run -e POSTGRES_PASSWORD=abdfdd3859a24c -d postgres

$ sudo docker run -e POSTGRES_PASSWORD=abdfdd3859a24c -d postgres

3. 运行 docker ps查看一下，是否安装成功

$ docker ps
permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json": dial unix /var/run/docker.sock: connect: permission denied

也会报错说权限问题

在命令前面加上sudo，再重新运行：$ sudo docker ps

meiyi@meiyi-Extensa-2511G:~/Downloads$ sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c9a07226ef7f postgres "docker-entrypoint.s…" About a minute ago Up About a minute 5432/tcp agitated_murdock

就安装成功了
