Hello Logstash Wizards, I’m struggling to understand how I can spin up a Logstash Docker container using bind-mounted settings ([see here](https://www.elastic.co/guide/en/logstash/current/docker-config.html)) to run the container with a config file on the local host. To explain: Let’s say I have this Logstash config file ( _ **/home/me/myconfig.conf** _ ) on my Ubuntu server: ``` input{ ...stuff... } filter{ ...more stuff... } output{ ...still more stuff... } ``` I want to force the Logstash Docker container to run this config file when it spins up. So I create a custom logstash.yml file ( _ **/home/me/logstash.yml** _ ): ``` http.host: 0.0.0.0 path.config: /usr/share/logstash/config/myconfig.conf ``` And I set ownership and permissions on these files like this: ``` root@ubuntuhost:/home/me# ls -l total 32 -rwxrwxrwx 1 logstash root 81 Jun 23 21:05 logstash.yml -rwxrwxrwx 1 logstash root 28 Jun 12 19:16 myconfig.conf root@ubuntuhost:/home/me# ``` A little overkill, but I don’t want any problems with the container being unable to access the files. Now all I have to do is spin up the container, and make sure it understands where to find these two files on my host system: ``` docker run -it -d \ -v /home/me/logstash.yml:/usr/share/logstash/config/logstash.yml \ -v /home/me/myconfig.conf:/usr/share/logstash/config/myconfig.conf \ logstash:latest ``` What I’ve determined from trial-and-error is that the container can successfully access and read the _ **logstash.yml** _ file, but cannot access the _ **myconfig.conf** _ file. So I must be doing something wrong with that binding. I thought that this part of the spin-up command… `-v /home/me/myconfig.conf:/usr/share/logstash/config/myconfig.conf \` …essentially created a logical link within the container to my local file. Can anyone see what I’m doing wrong? Thanks, -RAO ---

could [this](https://discuss.elastic.co/t/elasticsearch-index-not-created-after-adding-logstash-works-fine-with-filebeat-es/237374/14) be the issue ? ---

Thanks ptamba, No, I'm afraid that isn't the solution. When I apply the ":ro" ("Read Only") at the end of the filename, it actually generates an error: ``` 2020/06/25 20:47:37 Setting 'xpack.monitoring.elasticsearch.hosts' from environment. 2020/06/25 20:47:37 error: open /usr/share/logstash/config/logstash.yml: read-only file system ``` And when I drop the ":ro", it generates a massive Java error. Perhaps a bug in this version? (7.7.1) I've been Googling for a while today; there doesn't seem to be an example of spinning up a LS Docker Container while bind-mounting the local config file. ---

> [@redapplesonly](#): > > ```auto > -v /home/me/myconfig.conf:/usr/share/logstash/config/myconfig.conf \ > logstash:latest > > ``` i was referring to the config files. logstash in docker will look for the config in /usr/share/logstash/pipeline . your config uses /usr/share/logstash/config have you tried this instead? ``` -v /home/me/myconfig.conf:/usr/share/logstash/pipeline/logstash.conf \ logstash:latest ``` ---

...interesting! Yes, I will try over the weekend. Thanks, I'll let you know how it goes! ---

Yes, this worked, thank you! A word of warning to anyone who might be following in my footsteps... You have to make sure to set permissions on the local files for this to work. ---
