A nice Slash and Burn script for vCD

No Comments

WARNING!!! This will delete ALL VMs in your vCD!!!!!

Connect to your vCD with “Connect-CIServer ” and run the following:


Stop-CIVApp * -Confirm:$false
Remove-CIVApp * -Confirm:$false
sleep 5
Remove-OrgNetwork * -Confirm:$false

Then manually delete any gateway devices and then run the following to clean up all the orgs:


Set-OrgVdc -Enabled:$false
remove-OrgVdc -Confirm:$false
Set-Org -Enabled:$false 
remove-Org -Confirm:$false

Big thanks to my colleague Grant Voss for this awesome little cleanup script.

Creating and importing self-signed SSL certificates for vCD using keytool

No Comments
To create and import self-signed SSL certificates:
  1. Create an untrusted certificate for the HTTP service host with the command:keytool -keystore certificates.ks -storetype JCEKS -storepass passwd -genkey -alias http
  2. Enter the fully qualified domain name of the HTTP service host when prompted for your first name and last name.
  3. Create an untrusted certificate for the console proxy service host with the command:keytool -keystore certificates.ks -storetype JCEKS -storepass passwd -genkey -alias consoleproxy
  4. Verify that all the certificates have been imported, list the contents of the keystore file with the command:keytool -storetype JCEKS -storepass passwd -keystore certificates.ks -list
Notes:
  • By default, certificates are valid only for 3 months. To increase the duration, add the switch -validity number_of_days when creating your certificate.
  • After creating the certificates, you must run the /opt/vmware/vcloud-director/bin/configure script. This script prompts you for the SSL certificates. After you enter the required passwords, the vCloud Director service starts.

Creating and importing signed SSL certificates for vCloud Director using keytool

To create and import signed SSL certificates:
  1. Create the certificate.
    • To create an untrusted certificate for the HTTP service host, run the command:keytool -keystore certificates.ks -storetype JCEKS -storepass passwd –genkey -alias http
    • To create a certificate signing request for the HTTP service, run the command:keytool -keystore certificates.ks -storetype JCEKS -storepass passwd –certreq -alias http -file http.csrNote: This command creates a certificate signing request in the file http.csr.

       

    • To create an untrusted certificate for the console proxy service host, run the command:keytool -keystore certificates.ks -storetype JCEKS -storepass passwd -genkey -alias consoleproxy
    • To create a certificate signing request for the console proxy service, run the command:keytool -keystore certificates.ks -storetype JCEKS -storepass passwd -certreq –alias consoleproxy -file consoleproxy.csrNote: This command creates a certificate signing request in the file consoleproxy.csr.

       

  2. Send the certificate signing requests to your Certification Authority. You receive the SSL Certificates in an email.
  3. When you receive the signed certificates, import them into the keystore.
    • To import the Certification Authority’s root certificate into the keystore file, run the command:keytool -storetype JCEKS -storepass passwd -keystore certificates.ks -import –alias root -file root.cer
    • To import the Certification Authority’s intermediate certificates into the keystore file, run the command:keytool -storetype JCEKS -storepass passwd -keystore certificates.ks -import –alias intermediate -file intermediate.cer
    • To import the host-specific certificate for the HTTP service, run the command:keytool -storetype JCEKS -storepass passwd -keystore certificates.ks -import –alias http -file http.cer
    • To import the host-specific certificate for the console proxy service, run the command:keytool -storetype JCEKS -storepass passwd -keystore certificates.ks -import –alias consoleproxy -file consoleproxy.cer
  4. Verify that all the certificates have been imported, list the contents of the keystore file with the command:keytool -storetype JCEKS -storepass passwd -keystore certificates.ks -list

vCloud Director and SSL Certificates

VCD Cell SSL Certificates

The communication between the end-user and vCloud Director cell (either GUI or API) is encrypted and by default self-signed certificates are used. The certificate replacement procedure is explained in the documentation in a few simple steps. The problem I have encountered during big vCloud deployments is that enterprise security teams have specific procedures how to create and distribute certificates which is different from those described in the documentation.

The default procedure is following:

  • create untrusted certificates (private and public key) with JAVA keytool command (this must be done for vCloud Director GUI and console proxy)
  • create certificate signing requests
  • send the certificate signing requests to your Certification Authority
  • import the Certificate Authority root certificate
  • import signed certificates

In my case the certificates were created for me by the security team and I have received the private key in a .key file. On top of that the Certification Authority which signed the certificates was intermediate and was signed by two others. The chain was following: public Root CA -> intermediate CA1 -> intermediate CA2 -> VCD certificate.

vCloud Director JAVA keytool command does not allow private key import. Also the whole trusted chain for the certificate must be built so all the intermediate certificates are presented to the client browsers and the vCloud Director certificate can be validated. This has been achieved with the following procedure:

  1. Concatenate all CA certificates to create the whole chain:
    cat CA2.cer CA1.cer RootCA.cer > chain.crt
  2. With openssl create PKCS12 keystore with the private key, certificate chain and proper alias (first for the GUI):
    openssl.exe pkcs12 -export -in http.crt -inkey http.key -CAfile chain.crt -name http -passout pass:<password> -out http.pfx -chain
  3. Repeat for the console proxy:
    openssl.exe pkcs12 -export -in consoleproxy.crt -inkey consoleproxy.key -CAfile chain.crt -name consoleproxy -passout pass:<password> -out consoleproxy.pfx –chain
  4. Now we can import the two PKCS12 keystores into JAVA JCKS keystore with keytool:/opt/vmware/vcloud-director/jre/bin/keytool -importkeystore -deststorepass <password> -destkeystore certificates.ks -deststoretype JCEKS -srckeystore http.pfx -srcstoretype PKCS12 -srcstorepass <password>

    /opt/vmware/vcloud-director/jre/bin/keytool -importkeystore -deststorepass <password> -destkeystore certificates.ks -deststoretype JCEKS -srckeystore consoleproxy.pfx -srcstoretype PKCS12 -srcstorepass <password>
  5. We can check if the import was successful:
    /opt/vmware/vcloud-director/jre/bin/keytool -storetype JCEKS -storepass <password> -keystore certificates.ks –list
  6. Now we can import the new certificates to the vCloud Director cell. To do that we need first to stop it:service vmware-vcd stopNote this will interrupt all running VCD jobs. In order to do graceful shutdown followhttp://kb.vmware.com/kb/1033575
  7. Rerun configuration tool and point to the certificates.ks keystore created in steps 2 and 3. This will import the certificates./opt/vmware/vcloud-director/bin/configure
  8. Repeat for the other VCD cells
