Configuration must be available to the application without exposing credentials in source control, logs or browser code. What belongs in the runtime and which access controls matter?
A worked deployment uses a Dockerfile USER instruction and runs the application as UID 1001. An audit of the host still shows a rootful Docker daemon. The team assumed the Dockerfile changed both processes. What boundary did the instruction actually change?

I have an SNMP agent listening on a high-level port (16161) and I want to redirect traffic from the standard SNMP agent port 161. Easy iptables rule: iptables -t nat -A PREROUTING -p udp --dport 161 -j REDIRECT --to-ports 16161 However responses appear to come from port 16161 and are dropped by linux clients. I want to change the response's source port to 16
I have a Dockerfile that attempts to install the package google-chrome-stable among other packages in Ubuntu (v16 Xenial I think) as part of a Gitlab pipeline step. I have had no issues until recently, when the step started failing with this issue: Some packages could not be installed. This may mean that you have requested an impossible situation or if you a
