# Healthcheck configuration
|
|
#
|
|
# On roles that are running Traefik, Kamal will supply a default healthcheck to `docker run`.
|
|
# For other roles, by default no healthcheck is supplied.
|
|
#
|
|
# If no healthcheck is supplied and the image does not define one, then we wait for the container
|
|
# to reach a running state and then pause for the readiness delay.
|
|
#
|
|
# The default healthcheck is `curl -f http://localhost:<port>/<path>`, so it assumes that `curl`
|
|
# is available within the container.
|
|
|
|
# Healthcheck options
|
|
#
|
|
# These go under the `healthcheck` key in the root or role configuration.
|
|
healthcheck:
|
|
|
|
# Command
|
|
#
|
|
# The command to run, defaults to `curl -f http://localhost:<port>/<path>` on roles running Traefik
|
|
cmd: "curl -f http://localhost"
|

|
|
# Interval
|
|

# The Docker healthcheck interval, defaults to `1s`

|
# Max attempts
|
|
#
|
|
# The maximum number of times we poll the container to see if it is healthy, defaults to `7`
|
|
# Each check is separated by an increasing interval starting with 1 second.

# Port

# Cords for zero-downtime deployments
|
|
#
|
|
# The cord file is used for zero-downtime deployments. The healthcheck is augmented with a check
|
|
# for the existance of the file. This allows us to delete the file and force the container to
|
|
# become unhealthy, causing Traefik to stop routing traffic to it.
|
|
#
|
|
# Kamal mounts a volume at this location and creates the file before starting the container.
|
|
# You can set the value to `false` to disable the cord file, but this loses the zero-downtime
|
|
# guarantee.
|
|
#
|
|
# The default value is `/tmp/kamal-cord`
|
|
cord: /cord

# Log lines

|
# Number of lines to log from the container when the healthcheck fails, defaults to `50`
