Launching a InfluxDB container in docker with a default database name

Question

I'm running the following command to launch a InfluxDB container. This should create a new databse with the name defaultdb.

docker run -p 8086:8086 \
      -e INFLUXDB_DB=defaultdb -e INFLUXDB_ADMIN_ENABLED=true \
      -e INFLUXDB_ADMIN_USER=admin -e INFLUXDB_ADMIN_PASSWORD=adminpass \
      -e INFLUXDB_USER=user -e INFLUXDB_USER_PASSWORD=userpass \
      -v influxdb:/var/lib/influxdb \
      influxdb:latest 

But it doesnt create the default databse defaultdb. It creates the databse db0 instead of defaultdb. What I'm doing wrong?

Thanks in advance.

Answer 1

The issue was due to the INFLUXDB_ADMIN_ENABLED=true line.

The documentation states:

The administrator interface is deprecated as of 1.1.0 and will be removed in 1.3.0.

I was using the latest version which is (currently) the 1.4 so it seems that there was a problem with that deprecated INFLUXDB_ADMIN_ENABLED variable.

Removing that line, everything worked perfectly.

docker run -p 8086:8086 \
      -e INFLUXDB_DB=defaultdb \
      -e INFLUXDB_ADMIN_USER=admin \
      -e INFLUXDB_ADMIN_PASSWORD=adminpass \
      -e INFLUXDB_USER=user \
      -e INFLUXDB_USER_PASSWORD=userpass \
      -v influxdb:/var/lib/influxdb \
      influxdb:latest 

Answer 2

The problem is probably comming from the volume.

-v influxdb:/var/lib/influxdb

In particular, if you have previously created a database using the same command but without specifying the INFLUXDB_DB=defaultdb, this old database is overriding the container data via the old volume. To solve the issue, remove the old volume and rerun the command:

docker volume rm influxdb
