Containerized NSO Example - HA RAFT

Example usecase of running HA RAFT with Containerized NSO. This example is modified from the official example in example.ncs - high-availability/raft-cluster

Useage

The Makefile have the following target
build:
Build the container enviorment

certs:
Generate certificate for all nodes

install-certs:
Move the certifcate to the right place

NSO-vol/NSO*:
Set up specific node

deep_clean:
deep_clean will call the following target clean_log clean_run clean

clean:
clean will remove all the docker images

clean_cert:
clean all the relevent certification

clean_run:
clean the NSO-vol directory

clean_log:
clean the NSO-log-vol directory

clean_CDB:
clean the *.cdb file in NSO-log/run/cdb directory

stop:
stop all container with docker-compose

start:
start all container with docker-compose

compile_packages:
compile the packages inside the developer conainter

cli-c_nso1:
start Cisco style CLI on Leader NSO1

cli-c_nso2:
start Cisco style CLI on Seed NSO2

cli-c_nso3:
start Cisco style CLI on Member NSO3

cli-j_nso1:
start Juniper style CLI on Leader NSO1

cli-j_nso2:
start Juniper style CLI on Seed NSO2

cli-j_nso3:
start Juniper style CLI on Member NSO3

Use Case

1. Copy the development and production image in the images folder
2. Set Python dependency in requirements.txt
3. Set the dependency that need to be installed via yum and dnf in Dockerfile
4. Modify the "VER" and "ARCH" variable in Makefile. "VER" is the Containerized NSO version and "ARCH" is the CPU Architecture.
5. "make build" to build the enviorment and import the images
6. Start containers and bring up the HA with "make start"
7. Build the packages in the development images "make compile_packages"
8. Test the packages inside the production images "make cli-c_nso1/nso2" or Juniper CLI "make cli-j_nso1/nso2"
9. Check the HARAFT status via "show ha-raft" with "make cli-c_nso1/nso2"

$ make cli-c_nso1 
docker exec -it nso1 bash -c 'NCS_IPC_PORT=4561 ncs_cli -C -u admin'
