Influx

Description

This plugin enables you to send data to an InfluxDB in a pipeline.

Source Code: https://github.com/go-vela/vela-influx

Registry: https://hub.docker.com/r/target/vela-influx

Usage

NOTE:

Users should refrain from using latest as the tag for the Docker image.

It is recommended to use a semantically versioned tag instead.

Sample of emitting a pass/fail build metric:

steps:
  - name: write
    image: target/vela-influx:latest
    pull: always
    parameters:
      addr: https://influx.example.com
      database: vela
      name: build_report
      fields:
        build_status: ${VELA_BUILD_STATUS}

Sample of emitting a pass/fail build metric with custom tags:

steps:
  - name: write
    image: target/vela-influx:latest
    pull: always
    parameters:
      addr: https://influx.example.com
      database: vela
      name: build_report
      fields:
        build_status: ${BUILD_STATUS}
+     tags:
+       repo_name: ${VELA_REPO_FULL_NAME}
+       build_number: "${VELA_BUILD_NUMBER}"

Secrets

NOTE: Users should refrain from configuring sensitive information in your pipeline in plain text.

Internal

The plugin accepts the following parameters for authentication:

Parameter	Environment Variable Configuration
password	PARAMETER_PASSWORD, INFLUX_PASSWORD
username	PARAMETER_USERNAME, INFLUX_USERNAME

Users can use Vela internal secrets to substitute these sensitive values at runtime:

steps:
  - name: write
    image: target/vela-influx:latest
    pull: always
+   secrets: [ influx_username, influx_password ]
    parameters:
-     username: superSecretUsername
-     password: superSecretPassword
      addr: https://influx.example.com
      database: vela
      name: build_report
      fields:
        build_status: ${VELA_BUILD_STATUS}

This example will add the secret to the trigger_hello-world step as environment variables:

• DOWNSTREAM_TOKEN=<value>

External

The plugin accepts the following files for authentication:

Parameter	Volume Configuration
password	/vela/parameters/influx/password, /vela/secrets/influx/password
username	/vela/parameters/influx/username, /vela/secrets/influx/username

Users can use Vela external secrets to substitute these sensitive values at runtime:

steps:
  - name: write
    image: target/vela-influx:latest
    pull: always
    parameters:
-     username: superSecretUsername
-     password: superSecretPassword
      addr: https://influx.example.com
      database: vela
      name: build_report
      fields:
        build_status: ${VELA_BUILD_STATUS}

This example will read the secret value in the volume stored at /vela/secrets/

Parameters

NOTE:

The plugin supports reading all parameters via environment variables or files.

Any values set from a file take precedence over values set from the environment.

The following parameters are used to configure the image:

Name	Description	Required	Default	Environment Variables
addr	Influx instance to communicate with	true	N/A	PARAMETER_ADDR INFLUX_ADDR
database	database name on Influx instance to communicate with	true	N/A	PARAMETER_DATABASE INFLUX_DATABASE
fields	data fields to send along with the metric	true	N/A	PARAMETER_FIELDS INFLUX_FIELDS
log_level	set the log level for the plugin	true	info	PARAMETER_LOG_LEVEL INFLUX_LOG_LEVEL
name	name of metric sent to database on Influx instance	true	build_metrics	PARAMETER_NAME INFLUX_NAME
password	password for communication with Influx	false	N/A	PARAMETER_PASSWORD INFLUX_PASSWORD
tags	extra metadata to send along with the metric	false	N/A	PARAMETER_TAGS INFLUX_TAGS
username	user name for communication with Influx	false	N/A	PARAMETER_USERNAME INFLUX_USERNAME

Troubleshooting

You can start troubleshooting this plugin by tuning the level of logs being displayed:

steps:
  - name: write
    image: target/vela-influx:latest
    pull: always
    parameters:
+     log_level: trace
      addr: https://influx.example.com
      database: vela
      name: build_report
      fields:
        build_status: ${VELA_BUILD_STATUS}
