Docker image: influxdb

influxdb based on the official influxdb images, multiple architectures (amd64,arm64/v8), cloud ready, fully configurable through environment

Usage

UPDATE 2021-07-08 - BC breaking change!

The image is now using non-alpine base images and a small go utility (toml_update) to read, modify and write a valid toml configuration file.

• no more multi-line variables
• variable name order is no longer relevant
• -> configuration environment is much simpler and more "readable"

entrypoint_cmd=/entrypoint.sh
conf_templates="influxdb.conf.tmpl:/etc/influxdb/influxdb.conf"

Try it in 3 steps

1 create your own influxdb.env

docker run --rm -it drpsychick/influxdb:latest cat /default.env > influxdb.env
# check default configuration:
docker run --rm -it --env-file influxdb.env --name influxdb-1 drpsychick/influxdb:latest influxd config

2 configure it

Edit settings in influxdb.env to your needs:

• do not use spaces after the first = unless in quotes

IFX_GLOBAL=reporting-disabled=true

3 test and run it

Run in a separate teminal

docker run --rm -it --env-file influxdb.env --name influxdb-1 drpsychick/influxdb:latest --test
docker run --rm -it --env-file influxdb.env --name influxdb-1 --publish 8086:8086 drpsychick/influxdb:latest

Test the connection

curl http://localhost:8086/query --data-urlencode "q=SHOW DATABASES"

Configure it to your needs

You can use any IFX_ variable in your influxdb.env. They will be added to the config during container startup.

Example

IFX_VAR1=coordinator.write-timeout="30s"
IFX_ANY_OTHER_NAME=coordinator.max-concurrent-queries=10

Beware:

Docker only support simple variables. No ", no ' and especially no newlines in variables.
