Unable to push to local device using local base image

I am trying to push an app that uses a custom base image to a local device.

# Dockerfile
FROM sswm_main

The base image sswm_main is local to my system:

$ docker images
REPOSITORY    TAG        IMAGE ID            CREATED             SIZE
sswm_main     latest     07d2f46fa20a        About an hour ago   334MB

I am under the impression that this should work (similar to https://github.com/balena-io/balena-cli/issues/960). But when I push, I get this error:

$ sudo balena local push abcd123.local -f -s .

What am I doing wrong here?

Hi! The base image would need to be locally available on the device for this to work. So you would have to either push it up to a public repo on DockerHub, or save it to a tar file and load it on the device, or build it once on the device itself. The CLI doesn’t have a way to get the base image copied from your computer to the device automatically (though it does sound like something that would be nice to have).

Adding to what Pablo explained, you can copy the sswm_main docker image from your laptop/desktop to your device by running the following command line on your laptop/desktop:

docker save sswm_main | ssh root@abcd123.local -p 22222 balena-engine load

This works without further configuration if your device is running a development image of balenaOS. If it is running a production image, you’d need to configure ssh keys in config.json.

Thanks.

When I run that command, I get:

sh: balena-engine: command not found

Is that because I am running an old version of ResinOS? The device is currently running: Resin OS 2.12.7+rev1

Hi,

correct, we did rename balena to balena-engine few months ago. Can you try it with balena?

HTH,
Robert

Thanks. Since my last message, I updated to the latest Resin OS, and the command works.

Thanks everyone.

Hello pdcastro,

I use the command docker save sswm_main | ssh root@abcd123.local -p 22222 balena-engine load using my image and my credentials but after a while i take the response :
packet_write_wait: Connection to 192.168.1.100 port 22222: Broken pipe
Do you know why happens thats?

Thanks
