Updated resiliency gate
Updated resiliency gate script to consistently pass all gate stages, using ubuntu bionic image for node deployment. - Updated developer-onbording.rst with information on how to configure and run the resilency gate behind corporate proxy. - Updated the gate scripts to use the proxy configuration. - Updated up.sh to pull the hyperkube image as cache, to speed up and stabalize the initial kublet deployment of kubernetes cluster services. - Updated and added sleeps and retries in some of gate stages and scripts to avoid gate failures due to transient environment issues. - Updated the ubuntu base image for node deployments from xenial to\ bionic base image. - Added code in treadown-nodes stage to manually remove the etcd members: kubernetes and calico, since they still remain listed as etcd members on genesis node, even after genesis is torn down.

Running Resilency Tests Behind Corporate Proxy
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
If your development environment is behind a corporate proxy, you will need to
|
||||
update following files to add your envrionment's proxy information, dns, or
|
||||
possibly your internal ntp servers, in order to deploy airship:
|
||||
|
||||
* `charts/coredns/values.yaml`: Update the upstream coredns nameserver IPs
|
||||
to your internal DNS addresses.
|
||||
* `examples/basic/KubernetesNetwork.yaml`: Since resilency manifest uses
|
||||
the examples/basic environment configuration, you will need to Update
|
||||
the kubernetes network configuration in this folder. Update the upstream
|
||||
nameserver IPs to your internal DNS addresses. Add the http(s) proxy URL
|
||||
and additional_no_proxy list. Also, if your enviornment requires that,
|
||||
update the ntp server list to your internal ntp server addresses for
|
||||
more reliable time sync.
|
||||
* `tools/g2/templates/network-config.sub`: Update the upstream nameserver
|
||||
IPs to your internal DNS addresses.
