tutum-docker-influxdb

InfluxDB image

Usage

To create the image tutum/influxdb, execute the following command on tutum-docker-influxdb folder:

docker build -t tutum/influxdb .

You can now push new image to the registry:

docker push tutum/influxdb

Running your InfluxDB image

Start your image binding the external ports 8083 and 8086 in all interfaces to your container. Ports 8090 and 8099 are only used for clustering and should not be exposed to the internet.

docker run -d -p 8083:8083 -p 8086:8086 --expose 8090 --expose 8099 tutum/influxdb

Configuring your InfluxDB

Open your browse to access localhost:8083 to configure InfluxDB. Fill the port which maps to 8086. The default credential is root:root. Please change it as soon as possible.

Alternatively, you can use RESTful API to talk to InfluxDB on port 8086

Initially Create Database

Use -e PRE_CREATE_DB="db1;db2;db3" to create database named "db1", "db2", and "db3" on the first time the container starts automatically. Each database name is separated by ;`. For example:

docker run -d -p 8083:8083 -p 8084:8084 -e PRE_CREATE_DB="db1;db2;db3" tutum/influxdb:latest

SSL SUPPORT

By default, Influx DB uses port 8086 for HTTP API. If you want to use SSL API, you can set SSL_SUPPORT to true as an environment variable. In that case, you can use HTTP API on port 8086 and HTTPS API on port 8084. Please do not publish port 8086 if you want to only allow HTTTS connection.

If you provide SSL_CERT, system will use user provided ssl certificate. Otherwise system will create a self-signed certificated, which usually has an unauthorized cerificated problem, not recommend.

The cert file should be an combination of Private Key and Public Certificate. In order to pass it as an environment variable, you need specifically convert newline to \n(two characters). In order to do this, you can simply run the command awk 1 ORS='\\n' <your_cert.pem>. For example:

docker run -d -p 8083:8083 -p 8084:8084 -e SSL_SUPPORT="True" -e SSL_CERT="`awk 1 ORS='\\n' ~/cert.pem`" tutum/influxdb:latest

Clustering

Use :

• -e SEEDS="\"host1:8090\", \"host2:8090\"" to pass seeds nodes to your container.
• -e REPLI_FACTOR=x where x is the replicator factor of shards through the cluster (defaults to 1)
• -e FORCE_HOSTNAME="auto" to force the hostname in the config file to be set to the container IPv4 eth0 address (usefull to test clustering on a single docker host)
• -e FORCE_HOSTNAME="<whatever>" to force the hostname in the config file to be set to 'whatever'

Example on a single docker host :

• launch first container :

docker run -p 8083:8083 -p 8086:8086 --expose 8090 --expose 8099 \
  -e FORCE_HOSTNAME="auto" -e REPLI_FACTOR=2 \
  -d --name masterinflux tutum/influxdb

• then launch one or more "slaves":

docker run --link masterinflux:master -p 8083 -p 8086 --expose 8090 --expose 8099 \
  -e SEEDS="\"master:8090\"" -e FORCE_HOSTNAME="auto" \
  -d  tutum/influxdb
