Backup/restore postgres in docker container

Backup, restore postgres in docker container

Backup:
docker exec -t -u postgres your-db-container pg_dumpall -c > dump_`date +%d-%m-%Y"_"%H_%M_%S`.sql

Restore:
cat your_dump.sql | docker exec -i your-db-container psql -Upostgres

can i load data in dockerfile?

can i load data in dockerfile?

@rluts When creating dockerized containers, there are typically intermediate containers that do not persist any data into the next step of building. See this Stack Overflow question and accepted answer for an example.

With that said, after building your image, what you can do is import the data using the method proposed by @ChunAllen:
cat your_dump.sql | docker exec -i {docker-postgres-container} psql -U {user} -d {database_name}

After importation, create an image of that container, which will have a copy of your data.
You can then distribute this image, upload it to ECR, include it in a docker-compose, etc.

I was able to accomplish this using a dump file that was ~85 Gb's :)

for pg_restore

cat file | docker exec -i {docker-postgres} pg_restore -U {user} -d {database_name}

When I do

docker-compose exec -T db pg_restore --verbose --clean --no-acl --no-owner -U postgres -d engine < latest.dump

all I get is pg_restore: [archiver] input file is too short (read 0, expected 5)

Can someone help me, I new to docker-compose.

I know the engine db exists and its container is running, I can connect to it, and latest.dump also exists, is in the same folder Im running the command

Thx for a restore command :)

@eduardorr97: I think you need to place the file within the container (e.g. via a volume).

To restore your dump file with specified user and database_name

cat your_dump.sql | docker exec -i {docker-postgres-container} psql -U {user} -d {database_name}

this problem:
invalid command \":

Hey thanks for the reply, I actually remember solving this by using a different command than pg_restore, but I don't remember which command is was, this was long ago...

@eduadorr97: actually it would also be possible to keep the *.dump file outside of the container, but it is important that the container is actually running.

for pg_restore

cat file | docker exec -i {docker-postgres} pg_restore -U {user} -d {database_name}

thanks!! You save my day!

To restore your dump file with specified user and database_name
cat your_dump.sql | docker exec -i {docker-postgres-container} psql -U {user} -d {database_name}

This is pretty helpful

thanks

cat your_dump.sql | docker exec -i {docker-postgres-container} psql -U {user} -d {database_name} try this but got Internal server error while access the query page
