crictl inspect fails with multiple container-id input

[hassenius]

What happened:

When inputing multiple id's in crictl inspect the command fails

Example

crictl inspect -o go-template --template  '{{.status.id}} {{.info.pid}} {{index .info.runtimeSpec.annotations "io.kubernetes.pod.name"}}'  642733a12d491aff97dd225daf727019ad0d1431231514b9d34739cad4c372f9 1f7eae95409637b1b71d0d38a30ad13a7b7044638e6dc38cb6e2aefc53a9ef9f
FATA[0000] get the status of containers: execute template: failed to template data: template: tmplExecuteRawJSON:1:9: executing "tmplExecuteRawJSON" at <.status.id>: can't evaluate field status in type []interface {}

But individually they work just fine, showing that the issue arrises when doing mutiple ids

crictl inspect -o go-template --template  '{{.status.id}} {{.info.pid}} {{index .info.runtimeSpec.annotations "io.kubernetes.pod.name"}}'  642733a12d491aff97dd225daf727019ad0d1431231514b9d34739cad4c372f9

crictl inspect -o go-template --template  '{{.status.id}} {{.info.pid}} {{index .info.runtimeSpec.annotations "io.kubernetes.pod.name"}}'  1f7eae95409637b1b71d0d38a30ad13a7b7044638e6dc38cb6e2aefc53a9ef9f

What you expected to happen:

For it to succeed as command suggests

crictl inspect -h
NAME:
   crictl inspect - Display the status of one or more containers

USAGE:
   crictl inspect [command options] CONTAINER-ID [CONTAINER-ID...]

How to reproduce it (as minimally and precisely as possible):

Try crictl inspect with multiple IDs

Anything else we need to know?:

Environment:

• Container runtime or hardware configuration: crictl version v1.31.1

@hassenius thank you for the report! You actually have to change the template to include a range for multiple results, for example:

> sudo crictl inspect -o go-template --template  '{{range .}} {{.status.id}} {{.info.pid}} {{index .info.runtimeSpec.annotations "io.kubernetes.pod.name"}} {{end}}' 047150947add7f496667d544eb95a2ed08289ca9210f7c0ec1ac6ba5f36e0c12 0c918f38a80852574f4289d880aa22cbae0cbf2ac329d2d8bd96513fbfc68013

The problem is that crictl will either create a single object or a list of objects depending on the inspect result.
