Is Docker with PostgreSQL safe enough to store data? Are there any constraints?

We are considering Docker for our projects, but we are wondering on how reliable is Dockerized PostgreSQL to store massive amount of data on different databases.

Just my 2 cents. Docker itself is quite stable. It would not impact the database stability.

Thanks, any advice on whether using volumes of binding mounts?, I’ve been looking for some success stories on this approach with no luck

You may take a look of the discussions in another question How does Docker Swarm handle database (PostgreSQL) replication?.

Hope it helps.
