Is there a way to disable docker image update checks?

[djismgaming]

I see Click to update buttons along all the docker containers for the hosts. Would like to disable the update checking feature, if possible. Will this affect rate limits in hub.docker.com?

Good news - I've added an option to disable this.

Set PULSE_DISABLE_DOCKER_UPDATE_CHECKS=true or use the --disable-docker-update-checks flag.

About rate limits: Pulse already caches registry responses for 6 hours per image, so you shouldn't hit rate limits unless you have many containers with different images. But if you prefer to disable the feature entirely, now you can.

This will be available in the next release.

Hello,

Thank you for your work on this.

I am just going to give my opinion but I think the Docker "Update button" is outside the scope of Pulse and shouldn't be here at all. I consider Pulse to be a monitoring / alerting / observation first software ("Read only"), so I'm not expecting any "Write" (orchestration) feature applied on my Nodes/VM. This also open potential security / safety / separation concerns.

Anyway, I see the flag has to be applied to each Agent. Is it possible to have a global flag on Pulse server to disable all?

Set PULSE_DISABLE_DOCKER_UPDATE_CHECKS=true or use the --disable-docker-update-checks flag.

I am using Pulse with Proxmox LXC. Where do I put these variables?

Thanks! This is great to see!

@eilko You'll need to make this a variable available in the LXC at runtime. For an Alpine LXC it seems to be /etc/profile.

I added via nano /etc/profile:

export PULSE_DISABLE_DOCKER_UPDATE_CHECKS=true

Rebooted the LXC and tried with this one and had "true" replied back:

echo $PULSE_DISABLE_DOCKER_UPDATE_CHECKS

Note: I do not run pulse in an LXC, I run it in a docker container so I can't let you know if it works for the LXC you're working with. Try and let us know. You could also add it to the systemd unit file for Pulse, if systemd is what your LXC uses.

in the latest 5.10 release PULSE_DISABLE_DOCKER_UPDATE_ACTIONS=true was mentioned. I have added this line to the /etc/pulse/.env file. And eventually the update button was gone. I have now also added PULSE_DISABLE_DOCKER_UPDATE_CHECKS=true to that file, with no additional success.

So it seems your LXC uses pulse as a docker image. In that case the variable needs to be given to the docker container at runtime.

Setting it up in the LXCs runtime will not apply to the docker container running inside the LXC container.
