you can run an addinational daocloud image to accelerate your pulling, check Daocloud Proxy

1.init server

mkdir -p $(pwd)/postgresql/data
podman run --rm \
    --name postgresql \
    -p 5432:5432 \
    -e POSTGRES_PASSWORD=postgresql \
    -e PGDATA=/var/lib/postgresql/data/pgdata \
    -v $(pwd)/postgresql/data:/var/lib/postgresql/data \
    -d docker.io/library/postgres:15.2-alpine3.17

2.use web console

podman run --rm \
  -p 8080:80 \
  -e 'PGADMIN_DEFAULT_EMAIL=ben.wangz@foxmail.com' \
  -e 'PGADMIN_DEFAULT_PASSWORD=123456' \
  -d docker.io/dpage/pgadmin4:6.15
And then you can visit 🔗[http://localhost:8080]


3.use internal client

podman run --rm \
    --env PGPASSWORD=postgresql \
    --entrypoint psql \
    -it docker.io/library/postgres:15.2-alpine3.17 \
    --host host.containers.internal \

You can add standard markdown syntax:

  • multiple paragraphs
  • bullet point lists
  • emphasized, bold and even bold emphasized text
  • links
  • etc.
...and even source code

the possibilities are endless (almost - including other shortcodes may or may not work)
