ntfy-alertmanager

A bridge between ntfy and Alertmanager.

Installation

Simply use go build or the docker image with docker-compose file. ntfy-alertmanager:latest is built from the latest tagged release while ntfy-alertmanager:dev is built from the master branch.

Configuration

You can specify the configuration file location with the --config flag. By default the configuration file will be read from /etc/ntfy-alertmanager/config. The format of this file is scfg.

ntfy-alertmanager has support for setting ntfy priority and tags. Define a decreasing order of labels in the config file and map those labels to tags or priority.

• For priority the first found value will be chosen.
• Tags are added together.

Example:

# http listen address
http-address :8080
# Log level (either debug, info, warning, error)
log-level info
# Optionally protect with HTTP basic authentication
user webhookUser
password webhookPass

labels {
    order "severity,instance"

    severity "critical" {
        priority 5
        tags "rotating_light"
    }

    severity "info" {
        priority 1
    }

    instance "example.com" {
        tags "computer,example"
    }
}

ntfy {
    # URL of the ntfy topic - required
    topic https://ntfy.sh/alertmanager-alerts
    # ntfy access control (https://ntfy.sh/docs/config/#access-control)
    user user
