Should we switch to Oracle boxes?

[kbens]

Oracle is now shipping their own vagrant boxes for Oracle Linux. Should we change to use these? I know JR did some awesome work on trimming down the size, etc on the box we currently use. But using the official box might be easier to maintain going forward.

http://yum.oracle.com/boxes/

Matt Tremblay (@mattt on slack) has come up with a starting point for this idea. I will reply with the Vagrant file example.

Currently we have to add a disk on the fly, which works but cleanup is not perfect yet. Vagrant destroy requires and additional folder deletion.

[kbens]

1. Update the box option in vagrant file to use Oracle Linux vagrant box
    # Define the box we'll be using and automatically download the latest version
    vmconfig.vm.box = "ol7-latest"
    vmconfig.vm.box_url = "https://yum.oracle.com/boxes/oraclelinux/latest/ol7-latest.box"
    vmconfig.vm.box_check_update = true

2. Add 2nd disk and extend volume group in vagrant file
    # add 2nd disk at 100GB
   disk  = "disk2.vmdk"
   config.vm.provider "virtualbox" do | p |
    unless File.exist?(disk)
     p.customize ['createhd', '--filename', disk, '--size', 100 * 1024]
    end
    p.customize ['storageattach', :id, '--storagectl', 'SATA Controller', '--port', 1, '--device', 0, '--type', 'hdd', '--medium', disk]
   end

   # extend default volume group to increase drive space
   $script = <<-SCRIPT
   echo #######Extending volume group...########
   echo -e "o\nn\np\n1\n\n\nw" | fdisk /dev/sdb
   pvcreate /dev/sdb1
   vgextend vg_main /dev/sdb1
   lvextend -l +100%FREE /dev/mapper/vg_main-lv_root
   xfs_growfs /dev/mapper/vg_main-lv_root
   SCRIPT
   vmconfig.vm.provision "shell", inline: $script

#It will add the 2nd disk to the vagrant home directory, which may not be ideal for some. I found this example of adding the disk
#to the vm's virtualbox folder, but I am not heavily versed in vagrant, so I was unable to get it working.

3. add missing packages and JR's ps-extras repo in vagrant file
   # install required packages
   $extras = <<-SCRIPT
   echo #######adding packages and repos...########
   curl -s https://packagecloud.io/install/repositories/jrbing/ps-extras/script.rpm.sh | bash
   yum install -y "aria2" "unzip" "samba" "samba-client" "samba-common"
   SCRIPT
   vmconfig.vm.provision "shell", inline: $extras"

Below is a modified version of the ps-vagabond vagrant file with the changes that has worked.

This does deserve revisiting. With PeopleTools 8.57 dropping and PI's shipping on it soon, we'll need to make some updates to the project anyway. To start with, we'd need to review the Packer scripts used to build the OEL box and see if we can move the build steps into Vagabond's provisioning.

Doing some work on this. Samba does not reliably start when building new PI's. Could not start Service[samba]: Execution of '/bin/systemctl start smb' returned 1

I have branch that is ready to test. oel-boxes has code changes in place to support the ol7-latest OEL Vagrant box from Oracle. @ostracize you can to build a PI with this branch and verify that the vagrant-vbguest issues go away when using the OEL box (#77).

[iversond]

Need to the output from the new functions when they are not run with DEBUG mode on. Output is pretty messy with these changes right now.

[iversond]

Taking another run at this. The official Oracle Vagrant boxes are not playing nice with adding a second disk so we have space for PeopleSoft. Looking at using the bento/oracle-7.7 box instead. Similar to the Oracle Vagrant boxes, they are updated more frequently and are vanilla.

Also looking to address #77 and the issues with the vbguest installation.

[iversond]

The changes for this were committed to master with PR #88. Closing this issue.
