How often snapd handles updates for installed snaps. Setting an empty

A string that will be prepended to instance name to set the host name

in nagios. So for instance the hostname would be something like:
|
|
juju-myservice-0

If you're running multiple environments with the same services in them
|
|
this allows you to differentiate between them.

"description": |
|
|
YAML formatted associative array of sysctl values, e.g.:
|
|
'{kernel.pid_max : 4194303 }'. Note that kube-proxy handles
|
|
the conntrack settings. The proper way to alter them is to
|
|
use the proxy-extra-args config to set them, e.g.:
|
|
juju config kubernetes-master proxy-extra-args="conntrack-min=1000000 conntrack-max-per-core=250000"
|
|
juju config kubernetes-worker proxy-extra-args="conntrack-min=1000000 conntrack-max-per-core=250000"
|
|
The proxy-extra-args conntrack-min and conntrack-max-per-core can be set to 0 to ignore
|
|
kube-proxy's settings and use the sysctl settings instead. Note the fundamental difference between
|
|
the setting of conntrack-max-per-core vs nf_conntrack_max.

If false, NGINX ignores incoming X-Forwarded-* headers, filling them with the

request information it sees. Use this option if NGINX is exposed directly to
|
|
the internet, or it's behind a L3/packet-based load balancer that doesn't alter
|
|
the source IP in the packets.

Extra configuration to be passed to kubelet. Any values specified in this

Requires Kubernetes 1.10+.

The value for this config must be a YAML mapping that can be safely

merged with a KubeletConfiguration file. For example:

{evictionHard: {memory.available: 200Mi}}
