Docker File Sharing w/Cisco VPN
September 22, 2018
As I get started on my Docker journey I wanted to start with a simple application to get my feet wet. I chose the classic Example Voting App as it covered a few services, showed Docker Compose and had Kubernetes deployments already in place. When I tried to spin it up I received the following error: Error starting userland proxy: mkdir /port/tcp:0.0.0.0:32787:tcp:172.22.0.2:6379: input/output error Searching this specific issue leads in various directions, but then I saw a comment about having issues while on the corporate VPN, namely Cisco AnyConnect.
