To set up HTTPS and Basic Authentication for Alertmanager, follow these steps:
Generate SSL/TLS certificates for Alertmanager using a tool like Let’s Encrypt or OpenSSL.
Open the Alertmanager configuration file and add the following lines to enable HTTPS:
# Secure the web interface with HTTPS
tls_config:
cert_file: /path/to/cert.pem
key_file: /path/to/key.pem
Replace /path/to/cert.pem
and /path/to/key.pem
with the paths to your SSL/TLS certificate and key files.
$ go get -u github.com/prometheus/alertmanager/cmd/amtool
$ echo "myUser:$(openssl passwd -apr1)" > /path/to/alertmanager/htpasswd
Replace myUser
with the desired username.
# Authenticate users with HTTP basic authentication
route:
receiver: 'slack'
group_by: ['alertname']
group_wait: 30s
group_interval: 5m
repeat_interval: 30m
routes:
- match:
alertname: DeadMansSwitch
receiver: team-X-mails
continue: true
authentication:
basic_auth:
usersfile: /path/to/alertmanager/htpasswd
Replace /path/to/alertmanager/htpasswd
with the path to the Auth file created in step 4.
Now, when users access the Alertmanager web interface, they will be prompted to enter their username and password for authentication, and all communication will be secured over HTTPS.
