Introduction

One of the most powerful options in the ITS Private Cloud Command-Line interface (vss-cli) is the --columns global option. This option allows to show/hide any object attribute to customize the output of the vss-cli.

...

Example: List Virtual Machines disks and networks (compute vm ls)

In this example we need to get a list of virtual machines with the following attributes:

...

1. Run the following command to obtain the equivalent attributes:

   Code Block
   vss-cli --output yaml compute vm ls -c 1

2. Then identify object defined attribute disks and networks and their sub-attributes to require. In this case disks.label, disks.capacity_gib and networks.name.

3. Use jsonpath to extract the proper values:

   1. disks[*].capacity_gib

   2. disks[*].label

   3. networks[*].name

4. Join the columns in and add them to the --columns option as follows.

   Code Block
   vss-cli --columns moref,name,Folder=folder.path,"Disk Capacity=disks[*].capacity_gib,Disk Labels=disks[*].label,networks[*].name" compute vm ls

5. An example result would be as follows:

   Code Block
   moref name Folder Disk Capacity Disk Labels networks[*].name --------- -------------------------- -------------------- --------------- ------------------------ ------------------- vm-123455 2406Q-app-10-no-storage-qa Public > Client > QA 150.0, 100.0 Hard disk 2, Hard disk 1 VL-0253-EIS-VSS-CGN

Example: List Virtual Machines disks and networks (compute vm ls) and filter by folder path

In addition to the previous example, you can add the local --filter-by option to the ls command, in this case, to the vss-cli compute vm ls. Filtering with the vss-cli has the following format: <field_name>=<operator>,<value>. Where operator is any of the following:

...

Example: List Virtual Machines disks and networks (compute vm ls) and filter by multiple names

Filtering by multiple values is also possible with the --filter-by/-f option added to the ls command, in this case, to the vss-cli compute vm ls. Filtering with the vss-cli has the following format: <field_name>=<operator>,<value>. Where operator is any of the following:

...

1. Filtering works on any object attribute, in case of virtual machines, you can show available attributes to filter with:

   Code Block
   vss-cli --output yaml compute vm ls -c 1

2. Based on the previous output, name is the attribute to use, along with the in operator as follows:

   Code Block
   vss-cli --columns moref,name,Folder=folder.path,"Disk Capacity=disks[*].capacity_gib,Disk Labels=disks[*].label,networks[*].name" \ compute vm ls --filter-by "name=in,2407P-name1,2407P-name2"
