influxdb Configuration file can't be edited with nano inside of influxdb container

[kkoletz]

Hi everyone,

I've tried to setup my influxdb database and it's rights in order to use it with grafana and iobroker.
Now the admin and user account setup is working fine, also creating the database is fine.
Now I want to edit the influxdb config file to be able to access the newly created database, in my case called "iobroker" and also to set correctly the https certificates.
[http]
enabled = true
bind-address = ":8086"
auth-enabled = true
log-enabled = true
write-tracing = false
pprof-enabled = false
https-enabled = false
https-certificate = "/etc/ssl/influxdb.pem"

I want to edit the influxdb.conf file and it says that nano command not found.
How can I open the influxdb.conf file?
In case of IOTstack folder structure, in which directory is the influxdb.pem file?

root@3ddf65d363f3:~# cd /etc/influxdb/
root@3ddf65d363f3:/etc/influxdb# nano influxdb.conf
bash: nano: command not found
root@3ddf65d363f3:/etc/influxdb# ls
influxdb.conf
root@3ddf65d363f3:/etc/influxdb#

Unfortunately I could not find a proper documentation for this issue so all my hopes are on this wonderful community.
Thank you.

The answer is that, when influxdb is running in Docker, you do not edit the config file.

I understand that this will feel "wrong" if you've been using influxdb outside of Docker but that's the way it actually is.

Every option you can set in a config file can also be set with an environment variable. See the Influx documentation. For example:

[http]
auth-enabled = true

is:

INFLUXDB_HTTP_AUTH_ENABLED=true

If you are running IOTstack on the "old-menu" branch, you make changes to

~/IOTstack/services/influxdb/influxdb.env

If you are running the "master" branch (ie new menu) then you make the changes in the influxdb section of docker-compose.yml and, if you are diligent, you will also make parallel changes in

~/IOTstack/services/influxdb/service.yml

Whichever method you use, if you then

$ cd ~/IOTstack
$ docker-compose up -d influxdb

that will cause docker-compose to notice the environmental change and that, in turn, causes it to recreate the container with the new settings.

You might find this gist helpful.

Docker supports proper config file usage and we don't have to figure out a translation of config file -> compose environment variables. I execute docker run --rm influxdb influxd config > influxdb.conf to generate the default congfig file and remove all non mandatory stuff, and place under ./volumes/config, and map it to /etc/infludb/influxdb.conf which the default place where Influx engine is looking to get its configuration from.

  influxdb:
    container_name: influxdb
    image: "influxdb:latest"
    restart: unless-stopped
    ports:
    - "8086:8086"
    volumes:
    - ./volumes/influxdb/data:/var/lib/influxdb
    - ./volumes/influxdb/config/influxdb.conf:/etc/influxdb/influxdb.conf
