Use DescribeTags with a CLI

Example 1: To describe all tags for a single resource

The following describe-tags example describes the tags for the specified instance.

aws ec2 describe-tags \
    --filters "Name=resource-id,Values=i-1234567890abcdef8"

Output:

{
    "Tags": [
        {
            "ResourceType": "instance",
            "ResourceId": "i-1234567890abcdef8",
            "Value": "Test",
            "Key": "Stack"
        },
        {
            "ResourceType": "instance",
            "ResourceId": "i-1234567890abcdef8",
            "Value": "Beta Server",
            "Key": "Name"
        }
    ]
}

Example 2: To describe all tags for a resource type

The following describe-tags example describes the tags for your volumes.

aws ec2 describe-tags \
    --filters "Name=resource-type,Values=volume"

Output:

{
    "Tags": [
        {
            "ResourceType": "volume",
            "ResourceId": "vol-1234567890abcdef0",
            "Value": "Project1",
            "Key": "Purpose"
        },
        {
            "ResourceType": "volume",
            "ResourceId": "vol-049df61146c4d7901",
            "Value": "Logs",
            "Key": "Purpose"
        }
    ]
}

Example 3: To describe all your tags

The following describe-tags example describes the tags for all your resources.

aws ec2 describe-tags

Example 4: To describe the tags for your resources based on a tag key

The following describe-tags example describes the tags for your resources that have a tag with the key Stack.

aws ec2 describe-tags \
    --filters Name=key,Values=Stack

Output:

{
    "Tags": [
        {
            "ResourceType": "volume",
            "ResourceId": "vol-027552a73f021f3b",
            "Value": "Production",
            "Key": "Stack"
        },
        {
            "ResourceType": "instance",
            "ResourceId": "i-1234567890abcdef8",
            "Value": "Test",
            "Key": "Stack"
        }
    ]
}

Example 5: To describe the tags for your resources based on a tag key and tag value

The following describe-tags example describes the tags for your resources that have the tag Stack=Test.

aws ec2 describe-tags \
    --filters Name=key,Values=Stack Name=value,Values=Test

Output:

{
    "Tags": [
        {
            "ResourceType": "image",
            "ResourceId": "ami-3ac336533f021f3bd",
            "Value": "Test",
            "Key": "Stack"
        },
        {
            "ResourceType": "instance",
            "ResourceId": "i-1234567890abcdef8",
            "Value": "Test",
            "Key": "Stack"
        }
    ]
}

The following describe-tags example uses alternate syntax to describe resources with the tag Stack=Test.

aws ec2 describe-tags \
    --filters "Name=tag:Stack,Values=Test"

The following describe-tags example describes the tags for all your instances that have a tag with the key Purpose and no value.

aws ec2 describe-tags \
    --filters "Name=resource-type,Values=instance" "Name=key,Values=Purpose" "Name=value,Values="

Output:

{
    "Tags": [
        {
            "ResourceType": "instance",
            "ResourceId": "i-1234567890abcdef5",
            "Value": null,
            "Key": "Purpose"
        }
    ]
}

Example 1: This example fetches the tags for resource-type 'image'

Get-EC2Tag -Filter @{Name="resource-type";Values="image"}

Output:

Key         ResourceId            ResourceType Value
---         ----------            ------------ -----
Name        ami-0a123b4ccb567a8ea image        Win7-Imported
auto-delete ami-0a123b4ccb567a8ea image        never

Example 2: This example fetches all the tags for all the resources and groups them by resource type

Get-EC2Tag | Group-Object resourcetype

Output:

Count Name                      Group
----- ----                      -----
    9 subnet                    {Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription...}
   53 instance                  {Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription...}
    3 route-table               {Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription}
    5 security-group            {Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription...}
   30 volume                    {Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription...}
    1 internet-gateway          {Amazon.EC2.Model.TagDescription}
    3 network-interface         {Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription}
    4 elastic-ip                {Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription}
    1 dhcp-options              {Amazon.EC2.Model.TagDescription}
    2 image                     {Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription}
    3 vpc                       {Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription, Amazon.EC2.Model.TagDescription}

Example 3: This example displays all the resources with tag 'auto-delete' with value 'no' for the given region

Get-EC2Tag -Region eu-west-1 -Filter @{Name="tag:auto-delete";Values="no"}

Output:

Key         ResourceId            ResourceType Value
---         ----------            ------------ -----
auto-delete i-0f1bce234d5dd678b   instance     no
auto-delete vol-01d234aa5678901a2 volume       no
auto-delete vol-01234bfb5def6f7b8 volume       no
auto-delete vol-01ccb23f4c5e67890 volume       no

Example 4: This example obtains all the resources with tag 'auto-delete' with 'no' value and further filters in the next pipe to parse only 'instance' resource types and eventually creates 'ThisInstance' tag for each instance resources with value being the instance id itself

Get-EC2Tag -Region eu-west-1 -Filter @{Name="tag:auto-delete";Values="no"} | Where-Object ResourceType -eq "instance" | ForEach-Object {New-EC2Tag -ResourceId $_.ResourceId -Tag @{Key="ThisInstance";Value=$_.ResourceId}}

Example 5: This example fetches tags for all the instance resources as well as 'Name' keys and displays them in a table format

Get-EC2Tag -Filter @{Name="resource-type";Values="instance"},@{Name="key";Values="Name"} | Select-Object ResourceId, @{Name="Name-Tag";Expression={$PSItem.Value}} | Format-Table -AutoSize

Output:

ResourceId          Name-Tag
----------          --------
i-012e3cb4df567e1aa jump1
i-01c23a45d6fc7a89f repro-3
