docker postgres pgadmin local connection

Question

I have created an ubuntu image with nginx, php and postgres.

I want to connect the postgres database in my current image with pgadmin located on my loca

Answer 1

If pgAdmin is intended to be run wihtin same Ubuntu host/guest, then you need to link postgres container, so it could be resolved by a name.

1. Run a postgres container:

docker run --name some-postgres -e POSTGRES_PASSWORD=postgres -d postgres

2. Run pgAdmin container:

docker run -p 80:80 --link some-postgres -e "PGADMIN_DEFAULT_EMAIL=email@domain.com" -e "PGADMIN_DEFAULT_PASSWORD=postgres" -d dpage/pgadmin4

3. Now when adding new server in phAdmin web app, use some-postgres as server name

Note the --link some-postgres when we were bringing up the pgAdmin. This command makes postgres container visible to pgAdmin container.

Answer 2

You have to expose the postgres port in the container to you local system. You do this by running your container like this:

docker run -p 5432:5432 <name/id of container>

when connecting with your GUI client or CLI make sure to use the ip-address not localhost even if your ip-address is the localhost ip-address.

docker ps would give you the ip address your postgres container is on.

Answer 3

If you verified that PostgreSQL is running and you can connect there with local copy of PgAdmin...

The answer is simple: use host.docker.internal istead of localhost for the PgAdmin running inside the Docker

Answer 4

In my case, I had a PostgreSQL container, so I didn't change my container or create a docker-compose approach, I needed pgadming after few months to had installed PostgreSQL, so this is my approach:

1. docker inspect my_container_id_postgreSQL

2. The network assigned to PostgreSQL was:

   "Networks": { "docker_default": { "IPAddress": "172.18.0.2", ... } }

3. Ran my PGADMIN with --network command.

   docker run -p 85:80 --network docker_default -e 'PGADMIN_DEFAULT_EMAIL=user@domain.com' -e 'PGADMIN_DEFAULT_PASSWORD=SuperSecret' -d dpage/pgadmin4

4. Insert the Ip address into pgAdmin and the database credentials used in docker.

I hope this can be useful for someone. Regards.

Answer 5

After facing this issue for two days i was able to resolve that issue.

solution of this problem is already answered by peoples like do inspect

docker inspect CONTAINER_ID

but while running this command i got a-lot of logs like Host Config Config Network Settings etc. so i got confused which IPAddress to add in the pgAdmin connection because i tried 0.0.0.0 and config, host, networkSettings different -2 IPAddress in the logs but finally it works after trying a-lot.

it works with which IP, we have to add that network ip address (which we created to connect the postgres and pgAdmin.)

like in my case when i run :-

docker inspect postgres_container

 "NetworkSettings": {
        "Bridge": "",
        "SandboxID": "sdffsffsfsfsfsf123232e2r3pru3ouoyoyuosyvo8769696796",
        "HairpinMode": false,
        "LinkLocalIPv6Address": "",
        "LinkLocalIPv6PrefixLen": 0,
        "Ports": {
            "5432/tcp": [
                {
                    "HostIp": "0.0.0.0",
                    "HostPort": "5432"
                }
            ]
        },
        "SandboxKey": "/var/run/docker/231231Ad132",
        "SecondaryIPAddresses": null,
        "SecondaryIPv6Addresses": null,
        "EndpointID": "",
        "Gateway": "",
        "GlobalIPv6Address": "",
        "GlobalIPv6PrefixLen": 0,
        "IPAddress": "",
        "IPPrefixLen": 0,
        "IPv6Gateway": "",
        "MacAddress": "",
        "Networks": {
            "postgres": {
                "IPAMConfig": null,
                "Links": null,
                "Aliases": [
                    "postgres",
                    "0e2j3bn2m42"
                ],
                "NetworkID": "35rhlhl3l53l5hlh3523233k3k4k22l3hk2k4",
                "EndpointID":"b3424n43k52o2i4n235k1k4l2l4hj234f14n2",
                "Gateway": "192.168.16.1",
                "IPAddress": "192.168.16.2",
                "IPPrefixLen": 20,
                "IPv6Gateway": "",

so we have to add the NetworkSettings -> Network -> Postgres(mine created network) -> IPAddress i.e. "IPAddress": "192.168.16.2".

After adding this ip it will work.

I hope it will help.

I included this in the docker yaml file to get the database and pgAdmin:

database:
    image: postgres:10.4-alpine
    container_name: kafka-nodejs-example-database
    environment:
      POSTGRES_USER: ${POSTGRES_USER}
      POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
    expose:
      - "5432"
    ports:
      - 8000:5432
    volumes:
      - ./services/database/schema.sql:/docker-entrypoint-initdb.d/1-schema.sql
      - ./services/database/seed.sql:/docker-entrypoint-initdb.d/2-seed.sql
  pgadmin:
    image: dpage/pgadmin4
    ports:
      - 5454:5454/tcp
    environment:
      - PGADMIN_DEFAULT_EMAIL=admin@mydomain.com
      - PGADMIN_DEFAULT_PASSWORD=postgres
      - PGADMIN_LISTEN_PORT=5454

The postgres username is alphaone and the password is xxxxxxxxxxx.

Do a docker ps to get the container id and then docker inspect <dockerContainerId> | grep IPAddress

eg: docker inspect 2f50fabe8a87 | grep IPAddress

Insert the Ip address into pgAdmin and the database credentials used in docker:
