Troubleshooting Common Issues
You might stumble upon these common issues while setting up PostgreSQL & pgAdmin in docker
1. Sometimes connection won’t be established between PostgreSQL container and pgAdmin.
Make sure the containers are all on the same Docker network. Check the accuracy of connection parameters such hostname, port, login, and password. Also, ensure that PostgreSQL is set up to allow connections.
docker run --name pg -e POSTGRES_USER=root -e POSTGRES_PASSWORD=pass -p 5432:5432 -d postgres
2. If you are facing issues when trying to execute certain queries or accessing specific tables.
Examine the user permissions in PostgreSQL. Check that the user connecting from pgAdmin has the relevant permissions.
3. A default database will be built and will not allow incoming connections if there isn’t one when PostgreSQL in a container starts. This causes issue when connecting with pgAdmin
healthcheck:
test: ["CMD-SHELL", "pg_isready -U postgres"]
