Variable assignment not happening

I am having a problem like this;

  root@B056HAP2865372:~# str="$(consul-template --version)"
  consul-template v0.18.1 (9c62737)
  root@B056HAP2865372:~# echo $str

  root@B056HAP2865372:~# consul-template --version | cut -d" " -f 2
  consul-template v0.18.1 (9c62737)

so the command $consul-template --version works, but I cant assign it to any variable or pipe it to some other command.

If it helps this machine is a LXC 2.9.3 container. It's a bash shell. I have no idea what I am doing wrong.

Your command is writing it on stderr. You can redirect stderr to stdout and then assign to a variable:

str="$(consul-template --version 2>&1)"
