QUESTION
I've got a Rails 5.2 application using ActiveStorage and S3 but I've been having intermittent timeout issues. I'm also just a bit more comfortable with shrine from another app.
I've been trying to create a rake task to just loop through all the records with ActiveStorage attachments and reupload them as Shrine attachments, but I've been having a few issues.
I've tried to do it through URL and through tempfiles, but I'm not exactly sure of the right steps to fetch the activestorage version and to get it uploaded to S3 and saved on the record as a shrine attachment.
I've tried the rake task here, but I think the method is only available on rails 6.
Any tips or suggestions?

QUESTION
I wish to move a large set of files from an AWS S3 bucket in one AWS account (source), having systematic filenames following this pattern:
...ANSWER
Answered 2021-Jun-15 at 15:28You can use sort -V command to consider the proper versioning of files and then invoke copy command on each file one by one or a list of files at a time.
ls | sort -V
If you're on a GNU system, you can also use ls -v. This won't work in MacOS.

QUESTION
I have three .snappy.parquet files stored in an s3 bucket, I tried to use pandas.read_parquet() but it only work when I specify one single parquet file, e.g: df = pandas.read_parquet("s3://bucketname/xxx.snappy.parquet"), but if I don't specify the filename df = pandas.read_parquet("s3://bucketname"), this won't work and it gave me error: Seek before start of file.
I did a lot of reading, then I found this page
it suggests that we can use pyarrow to read multiple parquet files, so here's what I tried:

QUESTION
I have users in a Cognito user pool, some of whom are in an Administrators group. These administrators need to be allowed to read/write to a specific S3 bucket, and other users must not.
To achieve this, I assigned a role to the Administrators group which looked like this:
ANSWER
Answered 2021-Jun-15 at 12:03The solution lies in the federated identity pool's settings.
By default the identity pool will provide the IAM role that it's configured with. In other words, one of either the "unauthenticated role" or the "authenticated role" that it's set up with.
But it can be told instead to provide a role specified by the authentication provider. That's what will solve the problem here.
- In the AWS console, in Cognito, open the relevant identity pool.
- Click "Edit identity pool" (top right)
- Expand "Authentication Providers"
- Under Authenticated Role Selection, choose "Choose role from token".
That will allow Cognito to specify its own roles, and you will find that the users get the privileges of their group.
QUESTION
I have different files in my s3. Now I want to get the files which starts with cop_ . To achieve that I have tried the below:-
ANSWER
Answered 2021-Jun-15 at 11:40You are referencing a FileInfo object when calling .startswith() and not a string.
The filename is a property of the FileInfo object, so filename.name.startswith('cop_ ') should work.
QUESTION
I have 2 buckets on the S3 service. I have a lambda function "create-thumbnail" that triggered when an object is created into an original bucket, if it is an image, then resize it and upload it into the resized bucket.
Everything is working fine, but the function doesn't trigger when I upload files more than 4MB on the original bucket.
Function configurations are as follow,
- Timeout Limit: 2mins
- Memory 10240
- Trigger Event type: ObjectCreated (that covers create, put, post, copy and multipart upload complete)
ANSWER
Answered 2021-Jun-15 at 11:35Instead of using the lambda function, I have used some packages on the server and resize the file accordingly and then upload those files on the S3 bucket. I know this is not a solution to this question, but that's the only solution I found
Thanks to everyone who took their time to investigate this.

QUESTION
I have the Jenkins node in Account A that builds the angular application For Deploying the dist folder I need to copy files from s3 to the angular instance. But the angular Instance is in Account B
Script:
aws --region us-west-2 ssm send-command --instance-ids i-xxxxxx --document-name AWS-RunShellScript --comment 'Deployment from Pipeline xxx-release-pipeline' --cloud-watch-output-config 'CloudWatchOutputEnabled=true,CloudWatchLogGroupName=SSMDocumentRunLogGroup' --parameters '{"commands":["aws --region us-west-2 s3 cp s3://xxxx/dist/*.zip /var/www/demo.com/html", "unzip -q *.zip"]}' --output text --query Command.CommandId
So when I run ssm send-command from node(in Account A) it shows Invalid Instance Id.
An error occurred (InvalidInstanceId) when calling the SendCommand operation
Jenkins node -> Account A Angular Instance(with ssm agent) -> Account B
In the pipeline for deploy stage I need to copy files from s3 to instance in Account B Is there a way to implement this use case in a better way with or without ssm?
...ANSWER
Answered 2021-Jun-15 at 09:56I don't think you can directly run run-command accross account. But you could run in through AWS Systems Manager Automation. In your automation document you can use aws:runCommand.
This is possible because SSM Automation supports cross-account and cross-region deployments.
