Cannot connect to the Docker daemon

[sachinborek]

I'm attempting to run a Docker container on OpenWRT, but I'm encountering an error. Is there a guide available for setting up Docker on a router?

"Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?"

[frollic]

well, is it ?

[flygarn12]

Docker only runs what can run on the installed machine to begin with.

And OpenWrt is so slim compared to Debian or Ubuntu so you pretty much can only run OpenWrt in OpenWrt if it actually existed a Docker daemon to OpenWrt.

Teltonika also told you this was a dead end, remember ?

Error installing libsystemd on router

Teltonika said "Docker is a dead end for this device & Our devices are a bit too underpowered to run docker properly. however, due to lack of free memory, very few docker container would start, only very small ones, and even if they did, their performance would not be great."

In your future posts, please make sure to include the output of ubus call system board to disclose the hardware/software details (and not steal people's time).

If an error message appears:

"Cannot connect to the Docker daemon at unix:///var/run/docker.sock. is the docker daemon running?"

You need to install dockerd package.

last reply is still valid.

if you would be using proper openwrt, but you're not - https://openwrt.org/faq/cannot_satisfy_dependencies

[psherman]

Vendor forks of OpenWrt are not supported in these forums -- there are too many unknowns about how they have modified the code, including the fact that they are using a different kernel version than would be found in the official OpenWrt version of the same 'name'.

The RUTX11 is not supported by OpenWrt. As such, this thread is closed since the only way forward for the OP is to reach out to the vendor.
