Raspberry Pi - Cannot install regctl about dockcheck HOT 3 CLOSED

I have an old rpi2 on which I recently installed docker so I just tried dockcheck and it failed. The workaround given above worked for me thanks! Amazing what docker can do!

from dockcheck.

This is due to the binaries from regclient are amd64 or arm64 architecture (rpi3, rpi4, rpiZ2). So if you've got an older Pi (or 32bit OS for other reasons) there's no binaries that supports it.

What you could do is a work-around - where you run regctl in a contianer and wrap it in a shell script. It's not the most elegant solution and it'll be slower than having the proper binary. But it works.

Copied from regclient/docs/install.md:

cat >regctl <<EOF
#!/bin/sh
opts=""
case "\$*" in
  "registry login"*) opts="-t";;
esac
docker container run \$opts -i --rm --net host \\
  -u "\$(id -u):\$(id -g)" -e HOME -v \$HOME:\$HOME \\
  -v /etc/docker/certs.d:/etc/docker/certs.d:ro \\
  ghcr.io/regclient/regctl:latest "\$@"
EOF
chmod 755 regctl

Test it with ./regctl --help and then either add the file to the same path as dockcheck.sh or in your path (eg. ~/.local/bin/regctl).

I might add this to the readme actually, have forgotten to worn on supporting older architecture.

Yeah I'm glad it worked - I tested it on a rpi2 myself just to be sure before suggesting :)

Added this to the readme going up in the next version.
