Before using the playbook scripts in the cicd/tests directory, modify the common.resource file in the cicd/tests/ directory according to your environment. The content to be changed is the part annotated with '#' below.

*** Settings ***
Library SSHLibrary
Library String

*** Variables ***
${HOME} /home/sdt-admin # host directory of build and deploy node
${DEPLOY_HOST} sdt-deploy # hostname of deploy node
${DEPLOY_USER} sdt-admin # username of deploy node
${DEPLOY_KEY} ${HOME}/.ssh/lfedge_deploy # private key in build node to access deploy node
${DEPLOY_PWD} password 
${PLAYBOOK_PATH} lf-edge/deploy/playbook # playbook path of build and deploy node
${MASTER_HOST} sdt-master # hostname of master node
${BUILD_HOST} sdt-build # hostname of build node
${BUILD_USER} sdt-admin # username of build node
${BUILD_KEY} ${HOME}/.ssh/lfedge_build # private key in build node to access build node
${EDGE_HOST1} jet03 # hostname of edge node#1
${EDGE_HOST2} jet04 # hostname of edge node#2
${EDGE_USER} edge # username of edge node
${EDGE_KEY} ${HOME}/.ssh/edge # private key in deploy node to access edge node

Note, the build node and deploy node must use the same username and playbook path. If you want to use different username or playbook path, robot framework scripts in the cicd/tests/ directory need to be modified. In addition, if there is no private key on the build or deploy host, use command ssh-keygen to create the private key, and use the command ssh-copy-id to copy the key to the destination node.(Please refer to the chapter Preparing Edge Nodes above for detailed usage of command ssh-keygen and ssh-copy-id.)
