prepare Azure management certification for Vagrant


On Linux


  • Creating certification
    1. openssl genrsa -out azureMgt.key 2048
    2. openssl req -new -key azureMgt.key -out azureMgt.csr
    3. openssl x509 -req -days 730 -in azureMgt.csr -signkey azureMgt.key -out tempAzureMgt.pem
    4. cat azureMgt.key tempAazureMgt.pem > azureMgt.pem
    5. openssl x509 -inform pem -in azureMgt.pem -outform der -out azureMgt.cer
    6. openssl pkcs12 -export -out azureMgt.pfx -in azureMgt.pem -inkey azureMgt.key -name "Azure Certification"
  • Uploading file azureMgt.cer to Azure management portal
  • Using file azureMgt.pem on your azure client side. for example, using this file in Vagrant (the pfx format has problem based on my testing).
  • Generating SSH key for vagarant to launch VM on azure.
    1. openssl req -x509 -nodes -days 1095 -newkey rsa:2048 -keyout azuresshkey.key -out azuresshcert.pem
    2. Change the permissions on the private key and certificate for security. chmod 600 azuresshcert.pem ; chmod 600 azuresshkey.key
    3. azuresshcert.pem is vm's ssh certifiction. azuresshkey.key is the ssh key that we use to access VM

On Windows

work on this later.
