Weave Scope for PKS

What?

./get-weave-scope-for-pks.sh | kubectl apply -f -

This will:

• download the spec from cloud.weave.works as documented
• patch them with the above mentioned changes
• apply those to your currently targeted cluster

To patch the upstream specs the bosh cli will be used, specifically the interpolate command with an ops-file holding the patches.

Note:

Keep in mind to enable priviliged containers in OpsManager.

Why?

For PKS deployed clusters some things in the specs provided by weave need to be changed. Currently those changes are:

• docker's socket is in /var/vcap/sys/run/docker/docker.sock
• weave net integration is specificaly disabled, as PKS comes with either NSX-T or flannel

Others solutions tested:

kustomize

While kustomize looks interesting, esp. because it will be integrated in kubectl directly, I ran into som issues:

• kustomize cannot use a URL that does not point to a git rope as a base
• kustomize can only patch Kind: List specs (that's what we get from weave) with JSON patches
• JSON patch doe not work well for replacing with arrays of objects
