Please edit your post and move it to the Logstash category where it belongs. I'm somewhat puzzled since the Logstash process you're starting in the container effectively runs as root, and it should be able to create /output inside the container. However, that's not really what you want to happen right? It seems your expectation is to use the output subdirectory of the current directory, but that won't work as you've written things. You need to use the `-w` to start a container in a particular directory. ---

I've moved the category to logstash. Yes , we want to create the output directory inside the container . But its throwing the error. sudo docker run -w -it --rm -v "$PWD": logstash logstash -f [//logstash.conf](https://logstash.conf) , adding -w whether it will write the output to current directory (adding -w), ---

> Yes , we want to create the output directory inside the container I still don't understand where you want the output file. Two options, pick out of them: - In /output. Then use an absolute path in the file output's `path` option. - In the output subdirectory of the directory from which you start the container. Then use the `-w` option to `docker run` so set the working directory of the container. That said, I'd general avoid using relative paths in Logstash configurations. > sudo docker run -w -it --rm -v "$PWD": logstash logstash -f [//logstash.conf](https://logstash.conf) , adding -w whether it will write the output to current directory (adding -w), The `-w` option takes a string argument, e.g. `-w /path/to/some/dir`. And why do you have double slashes in front of "logstash.conf"? ---

I tried with absolute path also but it was giving same error permission denied. There is no // before logstash. I'll try with -w option , i understand this will not log the output to the docker instead it will log in to the current directory where i run the docker. ---
