The BEST way to setup Postgres docker container using data only container
The BEST way to setup Postgres docker container using a data only container. Data only container is used to store DB data. Data will remain even if dbdata container is deleted. We use mount from dbdata inside db container.
I have used psql_client to test DB connection. It can be any container with application which is using DB.
docker search data
docker pull maxexcloo/data
docker inspect postgres
docker run --name dbdata -v /var/lib/postgresql/data maxexcloo/data
docker inspect dbdata
ls /var/lib/docker/volumes/fb0e84fd5338617110771836d155f2e7cc87d0951134e1bf9bb44db557698059/_data
docker run --name db --volumes-from dbdata -d postgres
docker ps -a
docker run --name my_app --link db:db -ti psql_client
cat /etc/hosts
psql -U -postgres -h db
create database test;
\q
exit
docker inspect dbdata
ls /var/lib/docker/volumes/fb0e84fd5338617110771836d155f2e7cc87d0951134e1bf9bb44db557698059/_data
