Hi folks - I’ve recently been trying to rebuild our test instance after an update with no luck. Googling/ChatGPT indicates that maybe something is wrong with the app.yml formatting, but I’ve not been able to suss it out. Here’s the stdout, which I realize is not that useful: x86_64 arch detected. WARNING: containers/app.yml file is world-readable. You can secure this file by running: chmod o-rwx containers/app.yml Ensuring launcher is up to date Your version of Launcher is ahead of origin Stopping old container app 2.0.20250226-0128: Pulling from discourse/base Digest: sha256:6f18aa2cd22bba0deb91d69194e577d4f96130ad555ae8ec646a8792cbfe37db Status: Image is up to date for discourse/base:2.0.20250226-0128 docker.io/discourse/base:2.0.20250226-0128 /usr/local/lib/ruby/gems/3.3.0/gems/pups-1.2.1/lib/pups.rb /usr/local/bin/pups --stdin 109:C 13 Jun 2025 15:20:04.997 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 109:C 13 Jun 2025 15:20:04.997 # Redis version=7.0.15, bits=64, commit=00000000, modified=0, pid=109, just started 109:C 13 Jun 2025 15:20:04.997 # Configuration loaded 109:M 13 Jun 2025 15:20:04.997 * monotonic clock: POSIX clock_gettime 109:M 13 Jun 2025 15:20:04.998 * Running mode=standalone, port=6379. 109:M 13 Jun 2025 15:20:04.998 # Server initialized 109:M 13 Jun 2025 15:20:04.999 * Loading RDB produced by version 7.0.7 109:M 13 Jun 2025 15:20:04.999 * RDB age 14 seconds 109:M 13 Jun 2025 15:20:04.999 * RDB memory usage when created 2.95 Mb 109:M 13 Jun 2025 15:20:05.007 * Done loading RDB, keys loaded: 3659, keys expired: 0. 109:M 13 Jun 2025 15:20:05.007 * DB loaded from disk: 0.008 seconds 109:M 13 Jun 2025 15:20:05.007 * Ready to accept connections 3649:C 13 Jun 2025 15:22:52.415 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 3649:C 13 Jun 2025 15:22:52.415 # Redis version=7.0.15, bits=64, commit=00000000, modified=0, pid=3649, just started 3649:C 13 Jun 2025 15:22:52.415 # Configuration loaded 3649:M 13 Jun 2025 15:22:52.415 * monotonic clock: POSIX clock_gettime 3649:M 13 Jun 2025 15:22:52.416 # Warning: Could not create server TCP listening socket *:6379: bind: Address already in use 3649:M 13 Jun 2025 15:22:52.416 # Failed listening on port 6379 (TCP), aborting. 109:M 13 Jun 2025 15:25:05.035 * 100 changes in 300 seconds.

I appreciate your help!

I think in your place I’d start deleting sections of this YML in a binary search to find the culprit. You have a couple of blank lines, and you have two ‘replace’ sections which you could perhaps remove one at a time. Start by removing major sections and hope you can converge on the problem.

Incidentally, I ran the app.yml file through a YAML linter and it didn’t find anything. I also tried rebuilding without any plugins active, and that didn’t make a difference.

Suggest you paste some or all of your YML file - take care redact passwords and access tokens. The output [image] ScottF_KNIME: Invalid run command filename (SyntaxError) does seem suspicious. My own YML file is very simple, no commands, but perhaps yours is complicated.

Thanks. The only thing I can see is that where I have templates/web.ratelimited.template.yml you have templates/web.ratelimited-whitelist.template.yml Just possibly there is a syntax error in that file? It would be, I think, at /var/discourse/templates/web.ratelimited-whitelist.template.yml Although there could equally be a syntax error in any of the other templates mentioned.

I’ve definitely narrowed it down to this file, which is for sure causing the boot failure - /var/discourse/templates/web.ratelimited-whitelist.template.yml which I’m pasting below (with IPs redacted): params: reqs_per_second: 12 burst_per_second: 12 reqs_per_minute: 200 burst_per_minute: 100 conn_per_ip: 20 run: - replace: filename: "/etc/nginx/conf.d/discourse.conf" from: /server.+{/ to: | geo $limit { default 1; XX.YYY.ZZ.ZZZ 0; # hubprod XXX.YY.ZZZ.ZZZ 0; # hubdev } map $limit $limit_key { 0 ""; 1 $binary_remote_addr; } limit_req_zone $limit_key zone=flood:10m rate=$reqs_per_secondr/s; limit_req_zone $limit_key zone=bot:10m rate=$reqs_per_minuter/m; limit_req_status 429; limit_conn_zone $limit_key zone=connperip:10m; limit_conn_status 429; server { - replace: filename: "/etc/nginx/conf.d/discourse.conf" from: "/location @discourse {/" to: | location @discourse { limit_conn connperip $conn_per_ip; limit_req zone=flood burst=$burst_per_second nodelay; limit_req zone=bot burst=$burst_per_minute nodelay; Is there anything in the run command here that looks off? YAML linting still looks OK.

Your indentation is just very slightly different from what I might expect. And you have a blank line at the end. But I don’t know if these are clues.

Thanks for your help @Ed_S, it turned about to be some poor indentation buried in the YAML file I mentioned above. Not sure why any of the linters didn’t pick up on it, but diffing the problem file versus one in production made the problem clear right away.

Thanks @Ed_S. I’ve attached the YML in the hopes there’s a clue there.
