* fn: runner status and docker load images
Introducing a function run for pure runner Status
calls. Previously, Status gRPC calls returned active
inflight request counts with the purpose of a simple
health checker. However this is not sufficient since
it does not show if agent or docker is healthy. With
this change, if pure runner is configured with a status
image, that image is executed through docker. The
call uses zero memory/cpu/tmpsize settings to ensure
resource tracker does not block it.
However, operators might not always have a docker
repository accessible/available for status image. Or
operators might not want the status to go over the
network. To allow such cases, and in general possibly
caching docker images, added a new environment variable
FN_DOCKER_LOAD_FILE. If this is set, fn-agent during
startup will load these images that were previously
saved with 'docker save' into docker.
* Rejig the build process
During a build, we check and rebuild any dependencies prior to
potentially using them.
Build:
- DIND (this only produces a new docker image, no local code changes)
- fnserver (built as part of the testing)
On master, if everything works, then we release the built artifacts,
if necessary:
- DIND (this pushes a docker image and a tag)
- fnserver (this builds the docker image and releases it, if necessary).
Fnserver is dealt with last by the release script: all previous steps
in CI use locally-run go tests rather than a docker file.
When a commit happens, we need to know (a) if we need to rebuild
a set of tools and artifacts (or whether we can continue to use
published ones); and (b) if we need to release new versions of
those tools, if all tests pass.
We do this by identifying the previous release tag on origin/master
(which is the release branch), then checking for changes between
that point at the current one.
Those changes may appear in various places in the tree: some simple
boolean rules work out whether the change means we need to rebuild
and rerelease.
* Make the fnproject/fnserver build use the latest dind
As docker bumps from 17.12.x, use whatever dind we just built.
* Use bash
* fn: add fn-test-utils image
New tester image that uses go-fdk for advanced test scenarios.
Right now, this is an enhanced 'hello/sleeper' rolled into one
that echos the received headers/env to allow writing test cases.
* Renamed a bunch of images to use fnproject org.
* Multi-stage build for Docker.
* Added tmp vendor dirs to gitignore.
* Run docker-build at beginning of test.
