## About
This directory contains a collection of scripts used to build and manage this
repository. If there are any issues regarding the intention of a particular
script (or even part of a certain script), please reach out to us.
It may help us either refine our current scripts, or add on new ones
that are appropriate for a given use case.
## DinD (dind.sh)
DinD is a wrapper script which allows Docker to be run inside a Docker
container. DinD requires the container to
be run with privileged mode enabled.
## Generate Authors (generate-authors.sh)
Generates AUTHORS; a file with all the names and corresponding emails of
individual contributors. AUTHORS can be found in the home directory of
this repository.
## Make
There are two make files, each with different extensions. Neither are supposed
to be called directly; only invoke `make`. Both scripts run inside a Docker
container.
### make.ps1
- The Windows native build script that uses PowerShell semantics; it is limited
unlike `hack\make.sh` since it does not provide support for the full set of
operations provided by the Linux counterpart, `make.sh`. However, `make.ps1`
does provide support for local Windows development and Windows to Windows CI.
More information is found within `make.ps1` by the author, @jhowardmsft
### make.sh
- Referenced via `make test` when running tests on a local machine,
or directly referenced when running tests inside a Docker development container.
- When running on a local machine, `make test` to run all tests found in
`test`, `test-unit`, `test-integration`, and `test-docker-py` on
your local machine. The default timeout is set in `make.sh` to 60 minutes
(`${TIMEOUT:=60m}`), since it currently takes up to an hour to run
all of the tests.
- When running inside a Docker development container, `hack/make.sh` does
not have a single target that runs all the tests. You need to provide a
single command line with multiple targets that performs the same thing.
An example referenced from [Run targets inside a development container](https://docs.docker.com/opensource/project/test-and-docs/#run-targets-inside-a-development-container): `root@5f8630b873fe:/go/src/github.com/moby/moby# hack/make.sh dynbinary binary cross test-unit test-integration test-docker-py`
- For more information related to testing outside the scope of this README,
refer to
[Run tests and test documentation](https://docs.docker.com/opensource/project/test-and-docs/)
## Release (release.sh)
Releases any bundles built by `make` on a public AWS S3 bucket.
For information regarding configuration, please view `release.sh`.
## Vendor (vendor.sh)
A shell script that is a wrapper around Vndr. For information on how to use
this, please refer to [vndr's README](https://github.com/LK4D4/vndr/blob/master/README.md)

# Integration Testing on Swarm
IT on Swarm allows you to execute integration test in parallel across a Docker Swarm cluster
## Architecture
### Master service
- Works as a funker caller
- Calls a worker funker (`-worker-service`) with a chunk of `-check.f` filter strings (passed as a file via `-input` flag, typically `/mnt/input`)
### Worker service
- Works as a funker callee
- Executes an equivalent of `TESTFLAGS=-check.f TestFoo|TestBar|TestBaz ... make test-integration-cli` using the bind-mounted API socket (`docker.sock`)
### Client
- Controls master and workers via `docker stack`
- No need to have a local daemon
Typically, the master and workers are supposed to be running on a cloud environment,
while the client is supposed to be running on a laptop, e.g. Docker for Mac/Windows.
## Requirement
- Docker daemon 1.13 or later
- Private registry for distributed execution with multiple nodes
## Usage
### Step 1: Prepare images
$ make build-integration-cli-on-swarm
Following environment variables are known to work in this step:
- `BUILDFLAGS`
- `DOCKER_INCREMENTAL_BINARY`
Note: during the transition into Moby Project, you might need to create a symbolic link `$GOPATH/src/github.com/docker/docker` to `$GOPATH/src/github.com/moby/moby`.
### Step 2: Execute tests
$ ./hack/integration-cli-on-swarm/integration-cli-on-swarm -replicas 40 -push-worker-image YOUR_REGISTRY.EXAMPLE.COM/integration-cli-worker:latest
Following environment variables are known to work in this step:
- `DOCKER_GRAPHDRIVER`
- `DOCKER_EXPERIMENTAL`
#### Flags
Basic flags:
- `-replicas N`: the number of worker service replicas. i.e. degree of parallelism.
- `-chunks N`: the number of chunks. By default, `chunks` == `replicas`.
- `-push-worker-image REGISTRY/IMAGE:TAG`: push the worker image to the registry. Note that if you have only single node and hence you do not need a private registry, you do not need to specify `-push-worker-image`.
Experimental flags for mitigating makespan nonuniformity:
- `-shuffle`: Shuffle the test filter strings
Flags for debugging IT on Swarm itself:
- `-rand-seed N`: the random seed. This flag is useful for deterministic replaying. By default(0), the timestamp is used.
- `-filters-file FILE`: the file contains `-check.f` strings. By default, the file is automatically generated.
- `-dry-run`: skip the actual workload
- `keep-executor`: do not auto-remove executor containers, which is used for running privileged programs on Swarm
