Health Checks

Health Checks can be set up per Ignite deployment to make sure that:

Traffic is only directed to containers that pass the check, and
New builds smoothly roll out without downtime

This is done by querying the containers periodically to make sure they’re alive and healthy. You can choose how to respond to a health check. For example, you may only want to respond successfully to a health check once your program has connected to its database.

Options

Protocol-Specific Options

Option	Example	Description
Path	`/health_check`	the HTTP path that should be queried to check if your service is healthy
Port	`8080`	the port that your service is running on

Advanced Options

Option	Default	Description
Initial Delay	5	How long Ignite should wait before sending the first health check
Interval	60	How long Ignite should wait (in seconds) between sending health checks
Timeout	10000	The maximum time, in milliseconds, that should be tolerated for receiving a response to the health check. If exceeded, the container will be determined as unhealthy
Maximum Failures	3	How many times the health check needs to fail for a container to be determined unhealthy

Creating Health Checks

Currently, Ignite only supports HTTP(s)-based health checks. When setting up a health check, you can choose the HTTP path to be queried to make sure the container is alive. To respond successfully to a health check, you must respond on the path specified when creating the health check with a HTTP 2xx response code, such as 200 or 204.

Using the Console

Navigate to an Ignite deployment
Select Health Check from the sidebar
Click Create Check in the top right

Using the CLI

# Interactively
hop ignite health new

# Non-interactively

hop ignite health new <deployment_id> \
 --path [path] \
 --port [port] \
 --initial-delay [seconds] \
 --interval [seconds] \
 --timeout [milliseconds] \
 --max-failures [number]
