[BUG] systemd-journald recognizes logs as blob #11681
Description
Description
I am using a systemd service wrapper to start my containers with docker compose. Up until now, the logs in journald looked as expected:
Mär 30 13:07:54 lmsman-rnddh01 docker[600]: application-1 | 2024/03/30 13:07:54 ...
Mär 30 13:07:54 lmsman-rnddh01 docker[600]: application-1 | 2024/03/30 13:07:54 ...
Mär 30 13:07:54 lmsman-rnddh01 docker[600]: application-1 | 2024/03/30 13:07:54 ...
After updating from 2.24.7 -> 2.26.1 the logs in journald are recognized as binary data:
Apr 03 09:19:00 lmsman-rnddh01 docker[612]: [238B blob data]
Apr 03 09:19:03 lmsman-rnddh01 docker[612]: [232B blob data]
Apr 03 09:19:04 lmsman-rnddh01 docker[612]: [252B blob data]
Steps To Reproduce
Create a systemd unit /etc/systemd/system/compose.service with the following content:
[Unit]
Requires=docker.service
After=docker.service
[Service]
WorkingDirectory=<path_to_docker-compose.yaml>
ExecStart=/usr/bin/docker compose up
ExecStop=/usr/bin/docker compose down
[Install]
WantedBy=multi-user.target
Start the service and view the logs:
systemctl daemon-reload && systemctl start compose.service && journalctl -u compose.service -f
