@gorgeous-egg-16927 can you help @chilly-garage-80867 here?
g
I’d guess that the YAML is malformed somehow. I can take a look if you send it along

I’m not sure how you have your program set up, but this works for me:
Copy code
import pulumi_kubernetes as k8s


# Omit a resource from the Chart by transforming the specified resource definition to an empty List.
def omit_namespace(obj, opts):
    if obj["kind"] == "Namespace" and obj["metadata"]["name"] == "istio-system":
        obj["apiVersion"] = "v1"
        obj["kind"] = "List"


k8s.yaml.ConfigFile(
    "istio-crd",
    file="<https://raw.githubusercontent.com/knative-sandbox/net-istio/master/third_party/istio-stable/istio-crds.yaml>"
)
k8s.yaml.ConfigFile(
    "istio-minimal",
    file="<https://raw.githubusercontent.com/knative-sandbox/net-istio/master/third_party/istio-stable/istio-minimal.yaml>",
    transformations=[omit_namespace]
)
Copy code
$ pip3 freeze
pulumi==2.10.1
pulumi-kubernetes==2.6.1
c
Ihaven’t tried the omit, let me give it a shot
g
Yeah, that 
istio-system
namespace is present in both manifests, so I omitted it from the second one
c
Thanks. Still learning Pulumi
so I used this
Copy code
## Omit Namespaces
def omit_istio_namespace(obj, opts):
    if obj["kind"] == "Namespace" and obj["metadata"]["name"] == "istio-system":
        obj["apiVersion"] = "v1"
        obj["kind"] = "List"

# Istio

istio_crd = ConfigFile(
    "istio_crd",
    file="<https://raw.githubusercontent.com/knative-sandbox/net-istio/master/third_party/istio-stable/istio-crds.yaml>",
)

istio_minimal = ConfigFile(
    "istio_minimal",
    file="<https://raw.githubusercontent.com/knative-sandbox/net-istio/master/third_party/istio-stable/istio-minimal.yaml>",
    opts=ResourceOptions(provider=k8s_provider),
    transformations=[omit_istio_namespace],
)
and got this
Copy code
Exception: invocation of kubernetes:yaml:decode returned an error: error converting YAML to JSON: yaml: line 128: mapping values are not allowed in this context
    error: an unhandled error occurred: Program exited with non-zero exit code: 1
g
What versions are you using of 
pulumi
and 
pulumi-kubernetes
?
c
Copy code
$ pulumi plugin ls

Hmm…that error appears to be coming from the Kubernetes YAML parser, but I’m not sure why it’s working for me and not for you.
What’s the output if you run 
pip3 freeze
?
c
$ venv/bin/pip3 freeze Arpeggio==1.9.2 attrs==20.2.0 certifi==2020.6.20 chardet==3.0.4 dill==0.3.2 grpcio==1.32.0 idna==2.10 parver==0.3.0 protobuf==3.13.0 pulumi==2.10.1 pulumi-gcp==3.24.0 pulumi-kubernetes==2.6.1 pulumi-random==2.3.1 PyYAML==5.3.1 requests==2.24.0 semver==2.10.2 six==1.15.0 urllib3==1.25.10

🤔 I’m out of ideas on this. I searched that error message and it’s definitely related to malformed YAML, but I have no idea what would be different between our setups since the deps look identical
What platform are you running on? (Mac, Windows, Linux?)
c
Mac
I’ll email my main.py if it helps
g
Sure, sounds good
c

Update: this error turned out to be unrelated to the Istio CRDs — it was from a different yaml.ConfigGroup that was pointing to an HTML GitHub page rather than the raw YAML file.
