InfluxDB image
To create the image yaronr/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
tutum/influxdb:latest -> influxdb 0.10.1
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 tutum/influxdb
Docker
containers are easy to delete. If you delete your container instance and your cluster goes offline, you'll lose the InfluxDB store and configuration. If you are serious about keeping InfluxDB data persistently, then consider adding a volume mapping to the containers /data
folder:
docker run -d --volume=/var/influxdb:/data -p 8083:8083 -p 8086:8086 tutum/influxdb
Note: influxdb:0.9
is NOT backwards compatible with 0.8.x
. If you need version 0.8.x
, please run:
docker run -d -p 8083:8083 -p 8086:8086 tutum/influxdb:0.8.8
Open your browser to access localhost:8083
to configure InfluxDB. Fill the port which maps to 8086
. There is no default user anymore in version 0.9 but you can set auth-enabled: true
in the config.toml.
Alternatively, you can use RESTful API to talk to InfluxDB on port 8086
. For example, if you have problems with the initial database creation for version 0.9.x
, you can use the new influx
cli tool to configure the database. While the container is running, you launch the tool with the following command:
docker exec -ti influxdb-container-name /opt/influxdb/influx
Connected to http://localhost:8086 version 0.9.2.1
InfluxDB shell 0.9.2.1
>
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 8086:8086 -e ADMIN_USER="root" -e INFLUXDB_INIT_PWD="somepassword" -e PRE_CREATE_DB="db1;db2;db3" tutum/influxdb:latest
Alternatively, create a database and user with the InfluxDB 0.9 shell:
> CREATE DATABASE db1
> SHOW DATABASES
name: databases
---------------
name
db1
> USE db1
> CREATE USER root WITH PASSWORD 'somepassword' WITH ALL PRIVILEGES
> GRANT ALL PRIVILEGES ON db1 TO root
> SHOW USERS
user admin
root true
For additional Administration methods with the InfluxDB 0.9 shell, check out the Administration
guide on the InfluxDB website.
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 HTTPS connection.
If you provide SSL_CERT
, system will use user provided SSL certificate. Otherwise the system will create a self-signed certificate, which usually has an unauthorized certificate error, not recommend.
The cert file should be a 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
InfluxDB has plugin to support the Graphite Carbon API. This can be customized via the following variables:
- GRAPHITE_DB: name of the database the graphite plugin shall write the incoming metrics to
- GRAPHITE_BINDING: by default the graphite plugin listens on ':2003'. You can provide any
ipaddress:port
- GRAPHITE_PROTOCOL: 'udp' or 'tcp' (default)
- GRAPHITE_TEMPLATE: By default the template is set to
instance.profile.measurement*
which will parse a metric and create tags from it
docker run -d -p 8083:8083 -p 8086:8086 -p 2015:2015 -e ADMIN_USER="root" -e INFLUXDB_INIT_PWD="somepassword" -e PRE_CREATE_DB=my_db -e GRAPHITE_DB="my_db" -e GRAPHITE_BINDING=':2015' -e GRAPHITE_PROTOCOL="udp" -e GRAPHITE_template="tag1.tag2.tag3.measurement*" tutum/influxdb
More details on the configuration of InfluxDB's graphite plugin can be found at: https://github.com/influxdb/influxdb/blob/master/services/graphite/README.md
InfluxDB has a plugin to support the collectd network plugin. This can be customized via the following variables:
- COLLECTD_DB: name of the database the collectd plugin shall write the incoming metrics to
- COLLECTD_BINDING: by default the collectd plugin listens on ':25826'. You can provide any
ipaddress:port
- COLLECTD_RETENTION_POLICY: custom retention policy
- types.db: default types.db from collectd version 5.5.0 is provided. For custom types consider adding a volume mapping for /usr/share/collectd/types.db
docker run -d -p 8083:8083 -p 8086:8086 -p 25826:25826/udp -e ADMIN_USER="root" -e INFLUXDB_INIT_PWD="somepassword" -e PRE_CREATE_DB=my_db -e COLLECTD_DB="my_db" -e COLLECTD_BINDING=':25826' -e COLLECTD_RETENTION_POLICY="mypolicy" tutum/influxdb
More details on the configuration of InfluxDB's graphite plugin can be found at: https://github.com/influxdb/influxdb/blob/master/services/graphite/README.md
If you provide a UDP_DB
, influx will open a UDP port (4444 or if provided UDP_PORT
) for reception of events for the named database.
docker run -d -p 8083:8083 -p 8086:8086 --expose 8090 --expose 8099 --expose 4444 -e UDP_DB="my_db" tutum/influxdb
# (make sure firewall allows ports 8088, 8089)
docker run -p 8088:8088 -e FORCE_HOSTNAME=192.168.0.1:8088 -t tutum/influxdb
docker run -p 8089:8088 -e FORCE_HOSTNAME=192.168.0.1:8089 -e JOIN=192.168.0.1:8088 -t tutum/influxdb
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 (useful 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
