Thanks Russell! The AWS docs don't always have all the sample code you'd like to see, especially when it comes to filters. This bit of code helped me with the 'tag:key' filters which I was having trouble generating based on boto3 documentation. Nice Job :)

Russell,

As with the other poster thank you for the examples, they helped a lot. However I am looking for one other function... and I may have to split it up... but since these commands have to traverse the internet before producing output, they are very costly and I would like to use it only once.

That being said... my goal is to use describe_instances to display the configuration of multiple instances where I know the instance-id of approximately 8 and only specific tags of 2-3... I was trying to do something like this:

client=boto3.client("ec2")
filter1={"Name":"tag:Name","Values":["my_tag"]}
filter2={"Name":"instance-id","Values":["i-xxxxxxxxxxxxxxxxx"]}
client.describe_instances(Filters=[filter1,filter2])["Reservations"])

Unfortunately it did not work as planned. I believe what is happening is that "and" logic is applied when using the two filters this way. What I am looking to accomplish is an "or" statement so that I can get what I need without running such an expensive command more than once.

Do you know of such a way?

Thanks,

Scott

how would you make the filter case insensitive?

Can I exclude certain tags? Say I want to exclude instances which have a certain tag (which might, for example, indicate that they are to be scaled down), how would I do it?

Thank you so much, this took me forever to find this blog post, but now my code works!

Thank you ! Unfortunately as a newbie to coding the Boto3 documentation is very poor and confusing. Once again thank you for some clarity

Do you have incantations to return the value of a particular tag for a particular EC2 instance queried by name or instance-id? I promise I'm not asking you to answer my homework question. ;)

Right now I'm just using describe_instances with a Filter= on the tag:Name but that gives me the entire set of instance metadata when I really only care about one particular tag.

Hi, I want to filter the particular instance & want to check whether particular instance is Running or not in AWS by using python boto3. You have any idea about this.?

How can I Tag an instance, while creating with boto3? I am doing this way.

instances = ec2.create_instances( ImageId=image_dict[image_name], MinCount=1, MaxCount=1, SecurityGroupIds=[securitygroup_dict[security_group]], SubnetId=subnet_dict[subnet_name], InstanceType="t2.micro" ) I want to add a tag to the instance

How can I get all details with out filtering like Group Name, Description etc. in Security group?

Hi As I see to get the instance metadata i need to use the filter function. but can it be used in a lambda function. Means I am using ec2 = boto3.resource('ec2', region_name='us-west-2') instances=ec2.instances.filter(Filters=[{'Name':'instance-state-name','Values':['running']}]) for instance in instances: print(instance.id,instance.instance_type) I am not getting any result in my lambda function

Thanks Russell! It does so much help!!

I want to list snapshots whose start time is less than 'somedate'. How do I mention <(less than) in filters of describe_snapshots

ec2.describe_snapshots(

         Filters=[         
     {
         'Name': 'start-time'}]

Hi Rusell,

I am using lambda with max 512 MB of memory. Lets say when i describe ecs services, is there a way I can filter result. Because I don't want entire description of service. Probably running count and pending count is all good for me. Yes I can write my own function to cascade with results, but I want to save compute time on lambda. Any suggestions ?

excellent !

is it possible to filter a tag name whose value might be 'webapp1' and 'webapp2' but not 'webapp3'(!= 'webapp3') how can we add a not in the filter statement?

Hi Russell,

Is there any way we can get all the openshfit cluster using boto3 from AWS.

Hi Russell,

How do i filter particular fields from a response.

What if i want to print particular fields from a describe_image response.

response = client.describe_images(ImageIds=[ami]) So reponse being a dictionary which captures the response, what if i want extract specific fields like imageid, imagelocation what shall i do

Thanks in advance

How can I filter all ec2 instances in all regions based on the ec2 tag?

I want to use two filter first will search name of the instances whose name started by ram and then if it is stopped , is this right ? ec2_result = ec2.describe_instances(Filters=[ {'Name': 'tag:Name', 'Values': ['?ram*'], 'Name': 'instance-state-name', 'Values': [ 'stopped', 'running' ] }, ])
