+# socat-docker
+
+A simple docker image based on alpine, which basically only socat.
+
+It can be used for example to proxy tcp connections to a socket and vice versa for bridging between network namespaced and host networking.
+
+This was especially developed to access node_exporter running as --net=host from a prometheus within a regular Docker network.
+
+UID:GID is random, but consistent across different socat-docker containers for effortless sharing of sockets via bind mounts.
