Reference: Checking Logs

Users may wish to check logs for errors or other issues by following these steps:

  • Enter the following commands:

docker compose exec server bash
cd ~/data/log

  • After this is done, users should be able to view logs the services produce

ls -al
ls -al *.log

  • Users may also grep for specific items, etc.

ls -al *.log | grep http
grep "error" *http* | more

  • Press Q to stop more

  • Additionally, users can tail the file and see the logs come in real time as an action is performed on the front-end:

tail -n 0 -f *
tail -n 0 -f *http*

  • Press Control + C to stop tail

  • To download some log files:

docker compose exec server bash
cd ~/data/log
mkdir export_dir
for file in $(ls -1 *.log | grep http); do cp "$file" export_dir; done
ls export_dir/
tar -zcf export_dir.tar.gz export_dir/
rm -rf export_dir/
cd -                        #Back to the project directory
mv ~/data/log/export_dir.tar.gz .
exit
mv ./export_dir.tar.gz ../  #Move the file out of the project folder
exit                        #Remember to ssh back in and delete export_dir.tar.gz later
scp -r -P 50001 <server_username>@<server_domain>:/home/esp/export_dir.tar.gz /Users/<your_username>/Downloads/

  • You can also do this outside of the container

docker compose logs --follow
