6.5. Deploying a container image and creating a RHEL virtual machine in vSphere

Procedure

1. Create a metadata.yaml file and add the following information to this file:

   instance-id: cloud-vm
   local-hostname: vmname

2. Create a userdata.yam file and add the following information to the file:

   #cloud-config
   users:
   - name: admin
     sudo: "ALL=(ALL) NOPASSWD:ALL"
     ssh_authorized_keys:
     - ssh-rsa AAA...fhHQ== your.email@example.com

   ssh_authorized_keys is your SSH public key. You can find your SSH public key in ~/.ssh/id_rsa.pub.

3. Export the metadata.yaml and userdata.yaml files to the environment, compressed with gzip, encoded in base64 as follows. You will use these files in further steps.

   export METADATA=$(gzip -c9 <metadata.yaml | { base64 -w0 2>/dev/null || base64; }) \
   USERDATA=$(gzip -c9 <userdata.yaml | { base64 -w0 2>/dev/null || base64; })

4. Launch the image on vSphere with the metadata.yaml and userdata.yaml files:

   1. Import the .vmdk image in to vSphere:

      $ govc import.vmdk ./composer-api.vmdk <_foldername_>

   2. Create the VM in vSphere without powering it on:

      govc vm.create \
      -net.adapter=vmxnet3 \
      -m=4096 -c=2 -g=rhel8_64Guest \
      -firmware=bios -disk="foldername/composer-api.vmdk” \
      -disk.controller=ide -on=false \
      vmname

   3. Change the VM to add ExtraConfig variables, the cloud-init config:

      govc vm.change -vm vmname \
      -e guestinfo.metadata="${METADATA}" \
      -e guestinfo.metadata.encoding="gzip+base64" \
      -e guestinfo.userdata="${USERDATA}" \
      -e guestinfo.userdata.encoding="gzip+base64"
      .. Power-on the VM:
      govc vm.power -on vmname

   4. Retrieve the VM IP address:

      HOST=$(govc vm.ip vmname)
