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"
Currently, only one CI build can be started at the same time due to we only have only one testing cluster. This PR aims to enable multiple concurrent builds can be triggered to reduce the waiting time for CI builds. The major changes listed below:
1. Each build generate unique images for testing and debugging
2. Check whether the testing cluster is being used by another build.
3. Cache docker image & go mod after build finished
4. Improve dockerfiles for reusing docker build cache
Consolidates the addition of the fetcher container to the pod into a new type FetcherConfig and takes care of serviceAccountName if not set. Also added PreStop lifecycle handler if pod set TerminationGracePeriodSeconds
This removes fluentd in favor of using fluentbit, which is lighter (in
memory usage) and seems to be more actively maintained.
Fluentbit's config file format is different from fluentd's. It also
doesn't support the same record modification stuff that fluentd
supports, so we have to change the influxdb query slightly. This
means that after an upgrade, the new CLI may won't work for querying older
logs. Hopefully, this slight breakage is acceptable; if users
really need older logs they can use the older CLI.
* Refactor specialization process
* Separate readiness and liveness probe to different routes
For newdeploy, readiness probe should check whether a fetcher specializes env container successfully or not. In this commit, fetcher returns the actual state of current specialization status instead of returning 200ok directly.
Java environment builder with support for Maven builds. Default build comman runs `mvn clean package` and picks up target/*with-dependencies.jar for function.
