Work with DynamoDB resource tagging using AWS Command Line Interface v2

Create a table with tags.

# Create a table with tags
aws dynamodb create-table \
    --table-name TaggedTable \
    --attribute-definitions \
        AttributeName=ID,AttributeType=S \
    --key-schema \
        AttributeName=ID,KeyType=HASH \
    --billing-mode PAY_PER_REQUEST \
    --tags \
        Key=Environment,Value=Production \
        Key=Project,Value=Analytics \
        Key=Owner,Value=DataTeam

List tags for a resource.

# Get the table ARN
TABLE_ARN=$(aws dynamodb describe-table \
    --table-name TaggedTable \
    --query "Table.TableArn" \
    --output text)

# List tags for the table
aws dynamodb list-tags-of-resource \
    --resource-arn $TABLE_ARN

Add tags to a resource.

# Add tags to an existing table
aws dynamodb tag-resource \
    --resource-arn $TABLE_ARN \
    --tags \
        Key=CostCenter,Value=12345 \
        Key=BackupSchedule,Value=Daily

Remove tags from a resource.

# Remove tags from a table
aws dynamodb untag-resource \
    --resource-arn $TABLE_ARN \
    --tag-keys Owner BackupSchedule

Filter tables by tags.

# Create another table with different tags
aws dynamodb create-table \
    --table-name AnotherTaggedTable \
    --attribute-definitions \
        AttributeName=ID,AttributeType=S \
    --key-schema \
        AttributeName=ID,KeyType=HASH \
    --billing-mode PAY_PER_REQUEST \
    --tags \
        Key=Environment,Value=Development \
        Key=Project,Value=Testing

# Wait for table to become active
aws dynamodb wait table-exists --table-name AnotherTaggedTable

# List all tables
echo "All tables:"
aws dynamodb list-tables

# Get ARNs for all tables
echo -e "\nFiltering tables by Environment=Production tag:"
TABLE_ARNS=$(aws dynamodb list-tables --query "TableNames[*]" --output text | xargs -I {} aws dynamodb describe-table --table-name {} --query "Table.TableArn" --output text)

# Find tables with specific tag
for ARN in $TABLE_ARNS; do
    TABLE_NAME=$(echo $ARN | awk -F/ '{print $2}')
    TAGS=$(aws dynamodb list-tags-of-resource --resource-arn $ARN --query "Tags[?Key=='Environment' && Value=='Production']" --output text)
    if [ ! -z "$TAGS" ]; then
        echo "Table with Production tag: $TABLE_NAME"
    fi
