For advanced developers this may provide a more comfortable developer environment (e.g. by allowing IDE-assisted debugging), but setting it up can be a bit more challenging.
Get the Voltha-go repository. Its assumed in these notes that voltha-go is checked out into ~/repos Other notes refer to ~/source being used. Update paths as needed.
mkdir ~/repos cd ~/repos git clone https://gerrit.opencord.org/voltha-go cd voltha-go
After installing Go on the MAC, the GOPATH environment variable should be set to ~/go. Create a symbolic link in the $GOPATH/src tree to the voltha-go repository:
mkdir -p $GOPATH/src/github.com/opencord ln -s ~/repos/voltha-go $GOPATH/src/github.com/opencord/voltha-go
Install dep for fetching go protos
mkdir -p $GOPATH/bin curl https://raw.githubusercontent.com/golang/dep/master/install.sh | sh
Pull and build dependencies for the project. This may take a while. This may likely update versions of 3rd party packages in the vendor folder. This may introduce unexpected changes. If everything still works feel free to check in the vendor updates as needed.
cd $GOPATH/src/github.com/opencord/voltha-go/ dep ensure
VOLTHA can now be built and run directly at the shell prompt:
go build rw_core/main.go go run rw_core/main.go
Or build a docker image:
make rw_core
A fatal error can possibly occur if VOLTHA is built and executed at this stage:
go run rw_core/main.go panic: /debug/requests is already registered. You may have two independent copies of golang.org/x/net/trace in your binary, trying to maintain separate state. This may involve a vendored copy of golang.org/x/net/trace.
Fix this by removing directory ~/go/src/go.etcd.io/etcd/vendor/golang.org/x/net/trace.
We are using dep (https://github.com/golang/dep) for package management. This means all the necessary dependencies are located under the vendor directory and checked in. Whenever a new package is added to the project, please run "dep ensure" to update the appropriate deb files as well as the vendor library.
To build the voltha core and other containers:
make build
To run the voltha core (example below uses docker compose to run the core locally in a container - replace <Host IP> with your host IP):
DOCKER_HOST_IP=<Host IP> docker-compose -f compose/rw_core.yml up -d
voltha-protos or voltha-lib-goIf you want to build/test using a local copy or voltha-protos or voltha-lib-go this can be accomplished by using the environment variables LOCAL_PROTOS and LOCAL_LIB_GO. These environment variables should be set to the filesystem path where the local source is located, e.g.
LOCAL\_PROTOS=$HOME/src/voltha-protos LOCAL\_LIB\_GO=$HOME/src/voltha-lib-go
When these environment variables are set the vendored versions of these packages will be removed from the vendor directory and replaced by coping the files from the specificed locattions to the vendor directory. NOTE: this means that the files in the vendor directory are no longer what is in the git repository and it will take manual git intervention to put the original files back.
Please refer to the README.md file under the python directory
Simulated OLT, ONU and rw_core can be build together:
make build
or they via be individually built:
make rw_core
make simulated_olt
make simulated_onu
In the example below we are using the docker-compose command to run these containers locally.
DOCKER_HOST_IP=<Host IP> docker-compose -f compose/docker-compose-zk-kafka-test.yml up -d DOCKER_HOST_IP=<Host IP> docker-compose -f compose/docker-compose-etcd.yml up -d DOCKER_HOST_IP=<Host IP> docker-compose -f compose/rw_core.yml up -d DOCKER_HOST_IP=<Host IP> docker-compose -f compose/adapters-simulated.yml up -d
You should see the following containers up and running
