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 local machine.
I have tried using docker inspector to try to use the image ip to make a connection with my local pgadmin but without much success. I've also tried configuring some ports on local to make connection work.
docker run \
-p 5432:5432 \
--name container-postgresdb \
-e POSTGRES_PASSWORD=admin \
-d postgres
docker run \
-p 5050:80 \
-e "[email protected]" \
-e "PGADMIN_DEFAULT_PASSWORD=admin" \
-d dpage/pgadmin4
Enter PgAdmin on localhost:80. Then add a server with:
name: container-postgresdb
host: host.docker.internal
database: postgres
user: postgres
password: admin
You can also use this to find out the host address (it will be listed as IPAddress in the output):
docker inspect container-postgresdb \
-f "{{json .NetworkSettings.Networks }}"
This other article might help with more info.
Unable to connect to server: could not translate host name "host.docker.internal" to address: Try again
It's a valid question don't know why people feel "doesn't seem possible to answer that question".
So, here's how I do what you are trying to do:
Pull postgres image from Docker Hub
docker pull postgres:latest
Run the container using the below command
docker run -p 5432:5432 postgres
Using docker's inspect command find the IP
Use that IP, PORT, Username, and Password to connect in PGADMIN
You can also do a simple telnet like below to confirm if you can access docker postgres container:
telnet IP_ADDRESS 5432
-p 5432:5432 then you don't need to find the container's IP you can use your host IP, or 127.0.0.1 or just localhost
docker exec -it <container-name> psql -U postgres it works, so I think the container runs fine? However I still can't access it using the IPAddress nor Gateway from docker inspect. How did you make it work? I'm using macOS MontereyIf 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
localhost to this?
/etc/hosts during installationWhat I have done success on windows 10 running docker for windows 1.12.6(9655), the step is like below:
Pull the latest postgres
docker pull postgres:latest
run the postgres containner:
docker run -d -e POSTGRES_USER=user -e POSTGRES_PASSWORD=password123 --name db-my -p 5432:5432 --restart=always postgres
Then installed the latest version of pgAdmin4 from pgadmin website
Run pgAdmin 4 create new server, and input as following Host: 127.0.0.1 Port: 5432 User name: user password: password123
docker-compose after publishing port 5432 (ports: 5432:5432)Alternatively, you could combine Postgres and Pgadmin in one docker-compose file, and login as user [email protected], pwd: admin. To add the Posgres server, use hostname postgres, port 5432.
version: '3'
services:
postgres:
image: postgres
hostname: postgres
ports:
- "6543:5432"
environment:
POSTGRES_USER: postgres
POSTGRES_PASSWORD: postgres
POSTGRES_DB: TEST_SM
volumes:

restart: unless-stopped
pgadmin:
image: dpage/pgadmin4
depends_on:

docker network ls, you'll see a bridge for the postgres-to-pgadmin network (mine is postgres_postgres). Then, you can docker network inspect postgres_postgres and see two containers, each with an ip/hostname. Take the one from Postgres (mine is postgres_db_1) to successfully connect from pgAdmin.
In my case I could solve the problem inspecting my postgre image through command
docker inspect CONTAINER_ID | grep IPAddress.
So, I used the docker ip address to config my pgadmin 4 connection and everything was fine. Thanks to @Afshin Ghazi
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:
- [email protected]
- 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:
localhost didn't work.
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 "[email protected]" -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.
Warning: The --link flag is a legacy feature of Docker. It may eventually be removed. Unless you absolutely need to continue using it, we recommend that you use user-defined networks to facilitate communication between two containers instead of using --link. I also did not have any luck with using --link to get my pgadmin container to talk to my postgres container. I can access the postgres from a local install of pgadmin however.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": "",

"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.
This worked for me on Ubuntu 18:
1- Run a postgres container
docker run -d -e POSTGRES_USER=user -e POSTGRES_PASSWORD=password123 --name my-postgres -p 5432:5432 postgres
2- Run a pgAdmin container
docker run --rm -p 5050:5050 thajeztah/pgadmin4
3- Get your local IP (in Ubuntu by ifconfig command)
4- Open localhost:5050 in your browser
5- Click on Servers >> Create >> Server...
6- In General tab, give it a name, for example: docker. In Connection tab, enter these fields:
Host name: The IP from 3
Username: user
Password: password123
7- Click on Save and now everything should work fine.
Note: If this didn't work, try "localhost" for the host name.
In order or find your IP of the container, use following command
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_name_or_id

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.
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:
docker inspect my_container_id_postgreSQLThe network assigned to PostgreSQL was:
"Networks": { "docker_default": { "IPAddress": "172.18.0.2", ... } }
Ran my PGADMIN with --network command.
docker run -p 85:80 --network docker_default -e '[email protected]' -e 'PGADMIN_DEFAULT_PASSWORD=SuperSecret' -d dpage/pgadmin4
Insert the Ip address into pgAdmin and the database credentials used in docker.
I hope this can be useful for someone. Regards.
When you start container you have network alias for it. Just use this alias in pgadmin UI. Like if you have the following docker compose config:
version: "3.5"
services:
postgres:
container_name: postgres-14
image: postgres:14.1
restart: unless-stopped
ports:
- "5432:5432"
environment:
- POSTGRES_HOST_AUTH_METHOD=trust
- POSTGRES_PASSWORD=root
- POSTGRES_USER=postgres
hostname: postgres
pgadmin:
container_name: pgadmin4
image: dpage/pgadmin4
restart: unless-stopped
ports:
- "80:80"
environment:
- POSTGRES_HOST_AUTH_METHOD=trust
- [email protected]
- PGADMIN_DEFAULT_PASSWORD=admin
hostname: pgadmin
You can add server with hostname: postgres
Here are the full steps that worked for me
Download and install pgadmin GUI tool
Run docker container: docker-compose up my-db.
From this command logs, note down ipv4 address and port. In my case, it's 0.0.0.0 and 5432.
docker-compose.yml file and note down POSTGRES PASSWORD
pgadmin gui
In connection tab:
ipv4 address in Hostname/addressportPOSTGRES PASSWORD in password
You can create a Docker bridge network to do this too.
$ docker network create pgnet

--name pg \
--network pgnet \
--publish 5432:5432 \

The Hostname/address used above is the name of the Postgres container given by --name pg
Are you using Window Subsystem LinuxWSL2 to run Docker and PgAdmin?
The steps I suggested is similar to what folks suggested. In my case I am using window environment
Step 1: Open CMD and type ipconfig and hit enter.
Step 2: Check WSL IPv4 Adress
Ethernet adapter vEthernet (WSL):
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : 3bd9::997b:b52a::fe80::65b3%63
IPv4 Address. . . . . . . . . . . : 172.172.172.1 // use the IP as host/address
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Step 3: Open PgAdmin from the browse and create a server
Step 4:
// Here it depends on your desired config mine is the following
Server: postgres
host address: IPv4 Address(step 2)
username: postgress(username for postgress)
password: password(password for postgress)
I spend two days to figure out what was wrong, I hope someone will find it helpful

To find the correct ip for your container, execute the following commands:
Check container ID:
docker ps
To check the correct IP of your container:
docker inspect <ID_CONTAINER> | grep "IPAddress"
The configuration of both PostgreSQL and PgAdmin with Docker are simple, if not right, I recommend redoing the configuration from scratch, if your problem is deeper.
Here is a script I developed to solve this problem. script-sh/install-docker-postgres-and-pgadmin
For macOS IPs of postgres and pgadmin4 are different from the ones docker inspect provides.
Type
docker-machine ls
Take a look at the name of the server on the left. It's default by default.
docker-machine ip default will IP you need to use for both, pgadmin4 in browser and for postgres in pgadmin4 settings.
If local host port 5432 already in use by another psql servers, change it when creating the container and in Pgadmin. 
Go to your container terminal on Docker Desktop and type hostname -I in case is linux to get the ip assigned to this machine, then go to your pgAdmin an try it out. @Rigoxls
hostname -iI did not connect with my container pg (dpage/pgadmin4 image) from browser on 0.0.0.0:9090 .
I ran this command :
docker run --name pg -p 9090:9090 -e PGADMIN_DEFAULT_EMAIL='faizan' -e PGADMIN_DEFAULT_PASSWORD='faizan' -d dpage/pgadmin4
Solution one :
First I tried to inspect the container for IP address
docker inspect pg
I got the container IP address "IPAddress": "172.17.0.3". http://172.17.0.3:9090 did not accessible.
Solution two :
And then I ran command without de-attached mode (-d removed)
docker run --name pg -p 9090:9090 -e PGADMIN_DEFAULT_EMAIL='faizan' -e PGADMIN_DEFAULT_PASSWORD='faizan' dpage/pgadmin4
# Output, it should be running on 9090.
Listening at: http://[::]:80
-p 9090:9090 did not work.
Finally I found the solution :
On some filesystems that do not support extended attributes, it may not be possible to run pgAdmin without specifying a value for PGADMIN_LISTEN_PORT that is greater than 1024. In such cases, specify an alternate port when launching the container by adding the environment variable, for example:
-e 'PGADMIN_LISTEN_PORT=5050'
Don’t forget to adjust any host-container port mapping accordingly.
Read more about it official doc
I added -e 'PGADMIN_LISTEN_PORT=9090' and worked for me.
You can try both solutions, it will definitely work for you.
I ran this, It worked for me
docker pull dpage/pgadmin4
docker run -p 9000:80 -e '[email protected]' -e 'PGADMIN_DEFAULT_PASSWORD=root' -d dpage/pgadmin4
The solution I tried and worked for me, was to create a docker compose file where I included postgress and pgadmin as services. For more details: Connecting pgadmin to postgres in docker
pgAdmin-4: version 6.12
I tried several answers here and in other places but nothing worked for me.
Here is the problem I had and the solution. I had a docker postgres running my machine and need to connect this server in pgAdmin.
All I need to do was to check the docker information and fill the server configs based on that in pgAdmin.
You can do this by opening your docker and going to dashboard and then selecting the postgres image you're using. There is a tab called Inspect click on that. Here you can get all the information about that postgres container.
Now open the pgAdmin and resister a server by right clicking on the servers -> Register -> Server.
choose a name for the server and click Connection tab.
Here we need to fill the data like host name/address, IP, ports and etc.
In docker Inspect tab, there is Ports section that you can get this data from, something like this:
So your host address based on this picture is 172.0.0.1 and port is 5873.
Other info like database, user and password is also available in Environment section in docker Inspect tab.
Now fill the other information click save in pgAdmin and it should work.
in my case just try to see the container name by docker ps
then just 
then docker inspect 311753dcc4bf which 311753dcc4bf id
Not sure how many people this is going to help but I had to stop the currently running database from my windows machine. Once I did it I was able to connect to postgres database running in container
Navigate to "C:\Program Files\PostgreSQL\15\bin" if you can run "pg_ctl" command
Run below command
.\pg_ctl.exe -D "C:\Program Files\PostgreSQL\15\data" stop
Hope this helps
brew services stop postgresql. This fixed it for me.docker composeto create your containers, just use the service name of your database as hostname. I.e. if your service name ispostgresql-dbthen this is also your hostname to add in PGAdmin.
