wederbrand opened a new issue, #12197:
URL: https://github.com/apache/trafficserver/issues/12197
(this is the same as the stale issue #8955 but with a minimal reproducible
example)
After running the pre-built docker-image version 10.0.5 with a few minor
changes to records.yaml and logging.yaml ATS stops logging to stdout.
These are the two last lines from diags.log
````
[Apr 17 13:13:15.637] [ET_NET 7] NOTE: Traffic Server is fully initialized.
[Apr 17 13:18:35.441] [LOG_FLUSH] ERROR: Failed to write log to stdout:
[tried 555, wrote 0, Bad file descriptor]
````
It seems ATS is restarting and after that logging fails (or, perhaps,
logging fails so ATS restarts)
The only changes done in the attached files are
````
144c144
< server_ports: 8080 8080:ipv6
---
> server_ports: 8080
217c217
< pristine_host_hdr: 0
---
> pristine_host_hdr: 1
````
and
````
46,48c46,48
< - filename: squid
< format: squid
< mode: binary
---
> - filename: stdout
> format: common
> mode: ascii
````
This dockerfile does those changes, and nothing more.
````
FROM trafficserver/trafficserver:10.0.5
ADD logging.yaml /opt/etc/trafficserver/logging.yaml
ADD records.yaml /opt/etc/trafficserver/records.yaml
````
After building and starting a container logs appears on stdout for a couple
if minutes, 5 in my case but I'm sure it can differ.
I'm calling it periodically with watch, but any tool would be good
````
watch curl localhost:8080/hello/at/$(date +%s)
````
Below are the full records.yaml and logging.yaml
````
