When a function is created before the creation of the environment it's used, the newdeploy will not be able to create kube objs. Hence no function service record is inserted into the cache.
When getFuncSvc is called, the newdeploy tries to find the record in service cache in order to create kube objs with the same name used in previous kubeobjs creation. However, due to no record in the cache, a NotFound error is returned directly and causes the problem. To solve this, we use fn meta UID to ensure we always get the same obj name instead of getting it from the cache.
If the context of request is closed before ReverseProxy finishing writing
a huge response body to the response writer, the client will only receive
a truncated response body.
To solve this, move the context cancel after ReverseProxy finished.
To keep archive creation implementation simple and prevent any
confusion, we decided to remove `--keepurl` flag and embed URL
directly without downloading the file from it . In this way, we can
ensure consistent behavior in either package creation or spec file
creation. Also, it increases the portability of spec file.
1. The records are stored in redis which is not migratable to another cluster for the testing purposes.
2. Some of the requests fields are not recorded.
3. People should consider using https://github.com/buger/goreplay which is an existing mature and well-tested solution for testing purposes.
The function implementations of controller client package are
inconsistent. This PR lets functions reuse the functions
that already implemented and able to set additional headers to
request.
When `fn test` failed to retrieve logs from the function
pod, it turns to query logs from the log database. However,
the logdb type flag is not set to `fn test`, hence the logdb
type is empty (even without default value) and cause `fn logs`
returns an error due to unable to find the corresponding log
database type.
This PR adds logdb type flag to `fn test` to resolve the problem.
Jaeger preserves the trace data of router healthz endpoints
which is not so helpful for monitoring function metrics and
consumes storage to store such trace data.
This PR uses `GetStartOptions` to examine the request's path and
check if it's a request to healthz endpoint. If yes, skip and not
to trace it.
To follow 12-factor app rules, make jaeger collector endpoint
as an environment variable instead of CLI args. It's easier to
replace the value in different deployments. Also, we can utilize
valueFrom to get value from the configmap.
The helm pre-upgrade check failed due to the program tries to
check whether a multierr is a nil pointer instead of errors it contains.
This PR changes the way the program checks multierr in order not to block the upgrade.
Helm treats the single line "extraCoreComponentPodConfig" in
values.yaml as a key value pair config.
```
extraCoreComponentPodConfig:
```
And when a user tries to install helm with providing config
like following, it failed.
```
extraCoreComponentPodConfig:
nodeSelector:
serverless: fission
```
The root cause is that helm treats config in default values.yaml
and providing config as two different types of config, which is
key-value vs. value table. And so it's unable for helm to merge these
two configs even with the same key name.
This PR comments out the single line config in default values.yaml
to prevent the issue.
Before this PR, CLI functions fatal out when encountering error
instead of returning it. Such behavior makes it hard to reuse
the functions nor writing unit tests. This PR aims to make functions
return errors instead of error out.
Istio sidecar proxy blocks all requests sent through the reverse proxy
to the target service if the request.Host is not properly set to the
internal target service host. This PR sets the target service hosts
before establishing the proxy for the client in order to pass the
Istio sidecar proxy check.
Tensorflow Serving supports three kinds of API: predict, classify, regress. In order to fully support possible API types, this PR adds code to split the entry point with separator ":" to get model name and the API type separately. And append the API type to proxy URL when receiving the requests.
$ fission fn create --name t1 --pkg <pkg name> \
--env tensorflow --entrypoint "half_plus_two:regress"
The utility function GetMetadata uses wrong flag text to get the resource namespace and could cause the wrong results returned from the API server. This PR changes the function signature that allows users to pass in the flag text in order to get the correct value.
