Error occurred after transferring docker images to another device.

[Mojy0715]

I am trying to transfer docker image built from my laptop to another computer without internet connect.

The way I have done it:

1. Building the image on my laptop.
2. docker save to get the .tar file of the image
3. Copy the .tar file into a USB flash drive
4. Connect USB flash drive and copy the .tar file to the other computer without internet connection
5. docker run image
6. docker exec -it [CONTAINER ID] psql -U postgres (I have not changed any config, other than setting either POSTGRES_PASSWORD=password or POSTGRES_HOST_AUTH_METHOD=trust for testing)

and I got psql: error: connection to server on socket "/var/run/postgresl/.s.PGSQL.5432" failed: FATAL: could not find tuple for opclass 1981. The postgres container running on my laptop is working fine.

docker logs does not show anything particular:

PostgreSQL Database directory appears to contain a database; Skipping initialization

also I installed docker & docker compose on the computer without internet connection through dpkg -i with the packages I got from https://download.docker.com/linux/ubuntu/dists/jammy/pool/stable/amd64/

Please do enlighten me. Thank you.
