[POC] Go code base for Contrail projects

This repository holds Go implementation for Contrail projects. The goal of this project is to realize Go-based implementation & etcd based such as Kubernetes in order to improve performance, scale and ease operation.

We are planning to add following sub components.

API Server ( python based VNC API Server equivalent)
Sync (ifmap, rabbitMQ related code equivalent but depends on etcd)
Agent (SchemaTransformer, Device Manager equivalent)
Code generation tool (generateDS equivalent)

Currently, this project is POC stage so any external/internal API or design subject to change up to community discussion.

Development setup

Step1. Install Go and docker

Step2. Go get contrail

go get -u github.com/Juniper/contrail

Note that go get -u github.com/Juniper/contrail/cmd/contrailutil fails because we don't commit generated code.

Step3. Install dependencies

make deps

Step4. Generate code

make generate

Step5. Install code

make install

Step6. Install test environment

# setup testenv using docker
make testenv
# you need wait db process up
make reset_db

Note that these commands use docker command and depending on your docker configuration they may require root permissions. See Docker Documentation for more info.

Try

Run processes
```
contrail -c sample/contrail.yml run 
```
Note that you can overwrite configuration parameters using environment variable with prefix "CONTRAIL_"

For example CONTRAIL_DATABASE_DEBUG is overwriting database.debug value.
```
CONTRAIL_DATABASE_DEBUG=true contrail -c sample/contrail.yml run
```
Individual processes can be enabled or disabled using the configuration parameters.

Run CLI

export CONTRAIL_CONFIG=sample/cli.yml
# Show Schema
contrailcli schema virtual_network
# Create resources
contrailcli sync sample/sample_resource.yml
# List resources
contrailcli list virtual_network --detail
# Delete resources
contrailcli delete sample/sample_resource.yml

For more cli command see CLI Usage,

Schema Files

Note that schema stored here is just a cache for helping development. Developers should make sure download latest schema from http://github.com/Juniper/contrail-api-client

JSON version stored in public/schema.json

Templates for code generation based on this schema are stored in tools/templates Template configuration You can add your template on template_config.yaml.

Testing

make test

You can print out full sql trace too.

CONTRAIL_DATABASE_DEBUG=true make test

Commands

Repository holds source code for following CLI applications:

contrail - contains API Server, Agent and Sync processes and Cluster service
contrailcli - contains API Server command line client
contrailschema - code generator by schema definitions
contrailutil - contains development utilities

Show possible commands of application:

contrail -h

Show detailed information about specific command:

contrail <command> -h

Keystone Support

API Server supports Keystone V3 authentication and RBAC. API Server has minimal Keystone API V3 support for standalone use case. See a configuration example
