Testing logstash configs with Docker
Now this is really not rocket science, but since I might do this more often, I don’t want to google every time.
Prepare your directories
|
1 2 3 4 5 6 |
./tmp # THIS IS YOUR WORKING DIRECTORY |- patterns/ # optional | |- patternfile1 # optional | |- patternfile2 # optional |- logs.log |- logstash.conf |
Prepare your logstash config
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
# logstash.conf input { file { path => '/stash/logs.log' } } filter { # whatever config you want to test grok { match => [ "message", "%{WHATEVER}" ] patterns_dir => '/stash/patterns' # optional :) } } output { stdout { codec => rubydebug } } |
Run logstash

docker run --rm -ti -v $(pwd):/stash logstash logstash -f /stash/logstash.conf |
Done.
Done. 🙂
