| vagrant ssh puppetserver01 \ | ||
| --command "sudo /opt/puppetlabs/bin/puppetserver ca list --all" | ||
| ``` | ||
| 4. Install Agents | ||
| ```bash | ||
| for NODE in node0{1..2}; do | ||
| vagrant provision $NODE --provision-with "bootstrap" | ||
| done | ||
| ``` | ||
| 5. Issue Certificate Requests | ||
| ```bash | ||
| for NODE in node0{1..2}; do | ||
| printf "\n$NODE: Testing connection (expect failure)\n" | ||
| vagrant ssh $NODE --command 'sudo /opt/puppetlabs/bin/puppet agent --test' | ||
| done | ||
| ``` | ||
| 6. Verify | ||
| ```bash | ||
| vagrant ssh puppetserver01 --command "sudo /opt/puppetlabs/bin/puppetserver ca list" | ||
| ``` | ||
| 7. Sign Certificates | ||
| ```bash | ||
| for NODE in node0{1..2}.local; do | ||
| printf "\nSigning $NODE\n" | ||
| vagrant ssh puppetserver01 --command \ | ||
| "sudo /opt/puppetlabs/bin/puppetserver ca sign --certname $NODE" | ||
| done | ||
| ``` | ||
| 8. Verify | ||
| ```bash | ||
| vagrant ssh puppetserver01 --command "sudo /opt/puppetlabs/bin/puppetserver ca list --all" | ||
| ``` | ||
| 9. Test Connectivity | ||
| ```bash | ||
| for NODE in node0{1..2}; do | ||
| printf "\n$NODE: Testing connection (expect success)\n" | ||
| vagrant ssh $NODE --command 'sudo /opt/puppetlabs/bin/puppet agent --test' | ||
| done | ||
| ``` | ||
| 10. Provision | ||
| ```bash | ||
| for NODE in node0{1..2}; do vagrant provision $NODE; done | ||
| ``` | ||
| 11. Test Results | ||
| ```bash | ||
| for NODE in node0{1..2}; do | ||
| vagrant ssh $NODE --command "curl --include localhost" | ||
| done | ||
