Usage of isotime in Naming custom Images for Oracle Cloud Infrastructure

[Anil Shenoy]

Hi All,

Can you please suggest what is the best way to use isotime and rename a custom image in OCI?

I have used the below and it worked fine.

"my.timevar": "WinImage-{{isotime \"2006-01-02\"}}",

But it not behaving vague when i use

"my.timevar": "WinImage-{{isotime \"2006-01-02 15-04-05\"}}",

"my.timevar": "WinImage-{{isotime 2 Jan 2006 15:04:05"}}"

"my.timevar": "WinImage-{{isotime \"02-Jan-06 03\_04\_05\"}}

and many other ways.

Can you please suggest an accurate one that will display the date and time both.

Best regards,

[Alvaro Miranda Aguilera]

Hi,

Thanks, i have used this, but this would not give a time stamp. This time 2006-01-02 03:04:05 (or any time that we mention)  will be associated in image. That's it.

{{isotime \"2006-01-02 03:04:05\"}}"

It works for me as documented: 

Template: 

{
"variables":
{
"myvar": "packer-{{isotime \"2006-01-02\"}}",
"myvar2": "packer-{{isotime \"2006-01-02 03-04-05\"}}",
"myvar3": "packer-{{isotime \"2006-01-02 03:04:05\"}}"
},
"builders": [
{
"type": "null",
"communicator": "none"
}
],
"provisioners": [
{
"type": "shell-local",
"inline": ["echo {{ user `myvar`}}",
  "echo {{ user `myvar2`}}",
  "echo {{ user `myvar3`}}"]
}
]
}

Output: 

$ PACKER_LOG=0 packer build isotime_formatting_example.json
null: output will be in this color.

==> null: Running local shell script: /var/folders/8t/0yb5q0_x6mb2jldqq_vjn3lr0000gn/T/packer-shell381620806

Build 'null' finished.

Hi,

Thank you very much. Tried and tested successfully. 

"myvar2": "packer-{{isotime \"2006-01-02 03-04-05\"}}"  

Works perfectly fine.

The name of the image observed is formatted as expected:- 

OCI-Image-2020-02-28 09-53-19
