Pure bash healthcheck for stock promtail container

Raw

Healthcheck for stock promtail container.md

There's no wget and no curl (at least in the version I'm using at the moment). Here's a pure bash HTTP GET to /ready.

bash -c 'exec 3<>/dev/tcp/localhost/9080; \
echo -e GET /ready HTTP/1.1\\r\\nHost: localhost\\r\\n >&3; \
read line <&3; \
echo $line | grep -q "HTTP/1.1 200 OK"'
