Developers
Building the charm
make charm
Configuration
- extra_packages
- (string) Space separated list of extra deb packages to install.
- extra_sans
- (string) Space-separated list of extra SAN entries to add to the x509 certificate created for the load balancers.
- ha-cluster-dns
- (string) DNS entry to use with the HA Cluster subordinate charm. Mutually exclusive with ha-cluster-vip.
- ha-cluster-vip
- (string) Virtual IP for the charm to use with the HA Cluster subordinate charm Mutually exclusive with ha-cluster-dns. Multiple virtual IPs are separated by spaces.
- host
- (string) listen address
- 127.0.0.1
- install_keys
- (string) List of signing keys for install_sources package sources, per charmhelpers standard format (a yaml list of strings encoded as a string). The keys should be the full ASCII armoured GPG public keys. While GPG key ids are also supported and looked up on a keyserver, operators should be aware that this mechanism is insecure. null can be used if a standard package signing key is used that will already be installed on the machine, and for PPA sources where the package signing key is securely retrieved from Launchpad.
- install_sources
- (string) List of extra apt sources, per charm-helpers standard format (a yaml list of strings encoded as a string). Each source may be either a line that can be added directly to sources.list(5), or in the form ppa:<user>/<ppa-name> for adding Personal Package Archives, or a distribution component to enable.
- loadbalancer-ips
- (string) Space seperated list of IP addresses of loadbalancers in front of control plane. A common case for this is virtual IP addresses that are floated in front of the kubeapi-load-balancer charm. The workers will alternate IP addresses from this list to distribute load. If you have 2 IPs and 4 workers, each IP will be used by 2 workers.
- nagios_context
- (string) Used by the nrpe subordinate charms. 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.
- juju
- nagios_servicegroups
- (string) A comma-separated list of nagios servicegroups. If left empty, the nagios_context will be used as the servicegroup
- package_status
- (string) The status of service-affecting packages will be set to this value in the dpkg database. Valid values are "install" and "hold".
- install
- port
- (int) The port to run the loadbalancer
- 443
- proxy_read_timeout
- (int) Timeout in seconds for reading a response from proxy server.
- 600
