I currently have an InfluxdDB 1.7.9 Alpine Docker container running inside a Kubernetes cluster. The InfluxDB container spins up fine and I’m able to write data to it from my Telegraf containers running in the same cluster.
Whenever I shell into the InfluxDB container and try to execute any commands inside the DB I get the following error message:
“There was an error writing history file: open /.influx_history: permission denied”
When I check my ID in the shell I see this:
bash-4.4$ id
uid=100 gid=0(root) groups=0(root)
I can’t write anything in the / partition:
bash-4.4$ pwd
/
bash-4.4$ touch test
touch: test: Permission denied
Is it possible to configure the .influx_history file be written somewhere else? I have read/write access to the /var/lib/influxdb directory and wanted to write the .influxd_history file there but don’t know if this is even possible?
Hello @mohsin106 ,
I didn’t know the answer so I phoned a friend :p. His response:
" that user , uid=100, does not probably have a proper home env variable set. I assume that .influx_history will be written to the user home directory so he could just export an HOME=<somewhere_where_user_100_can_write> ( like /tmp or /var/lib/influxdb ) in the manifest starting the influx pod
I did start the official alpine 1.7.9 influxdb image and i can’t see that user 100 so either he is setting that user in the context of the pod on startup or is a custom image, in that case he could also set the home properly for that user at creation time in the dockerfile"
