frankjkelly opened a new issue #6836:
URL: https://github.com/apache/pulsar/issues/6836
**Describe the bug**
Setting PULSAR_PID_DIR="/tmp" but I see no "obvious" pid file in /tmp
directory
**To Reproduce**
Steps to reproduce the behavior:
1) Set PULSAR_PID_DIR e.g. in my Docker file
```
ENV PULSAR_PID_DIR="/tmp"
RUN export PULSAR_PID_DIR
```
2) Start Pulsar
```
echo "PULSAR_PID_DIR=${PULSAR_PID_DIR}"
/pulsar/bin/pulsar standalone
```
3) Wait
4) Check /tmp
**Expected behavior**
I would expect some kind of pid file (not sure what filename to expect as
it's not specified in the docs) e.g. ```pulsar.pid```
**Screenshots**
