How should I approach a Docker upgrade?
An upgrade needs a compatibility check, a tested release and a recovery path. Which changes deserve particular attention before the new version reaches production?
What needs backing up or preserving in Docker?
Recovery needs to recreate the working service and its required data after a machine or process is lost. Which artifacts and state need protection, and how should the restore be checked?
What should I check first when Docker fails?
A failure needs to be narrowed down before settings are changed or operations retried. Which evidence best separates application errors from environment and dependency problems?
How should I handle configuration and secrets in Docker?
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?

Measure application CPU, memory, I/O and startup work. Use layer caching to speed builds and small runtime stages to reduce distribution size, but do not equate a smaller image with faster requests. Check cgroup limits and storage behavior when performance differs from the host.

How can I improve Docker performance without guessing?
