Dynamodb local web shell does not load - amazon-web-services

I am running DynamoDB locally using the instructions here. To remove potential docker networking issues I am using the "Download Locally" version of the instructions. Before running dynamo locally I run aws configure to set some fake values for AWS access, secret, and region, and here is the output:
$ aws configure
AWS Access Key ID [****************fake]:
AWS Secret Access Key [****************ake2]:
Default region name [local]:
Default output format [json]:
here is the output of running dynamo locally:
$ java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb
Initializing DynamoDB Local with the following configuration:
Port: 8000
InMemory: false
DbPath: null
SharedDb: true
shouldDelayTransientStatuses: false
CorsParams: *
I can confirm that the DynamoDB is running locally successfully by listing tables using aws cli
$ aws dynamodb list-tables --endpoint-url http://localhost:8000
{
"TableNames": []
}
but when I visit http://localhost:8000/shell in my browser, this is the error I get and the page does not load.
I tried running curl on the shell to see if I can get a more useful error message:
$ curl http://localhost:8000/shell
{
"__type":"com.amazonaws.dynamodb.v20120810#MissingAuthenticationToken",
"Message":"Request must contain either a valid (registered) AWS access key ID or X.509 certificate."}%
I tried looking up the error above, but I don't have much choice in doing setup when running the shell merely in the browser. Any help is appreciated on how I can run the Dynamodb javascript web shell with this setting.
Software versions:
aws cli: aws-cli/2.4.7 Python/3.9.9 Darwin/20.6.0 source/x86_64 prompt/off
OS: MacOS Big Sur 11.6.2 (20G314)

DynamoDB Local Web Shell was deprecated with version 1.16.X and is not available any longer from 1.17.X to latest. There are no immediate plans for a new Web Shell to be introduced.
You can download an old version of DynamoDB Local < 1.17.X should you wish to use the Web Shell.
Available versions:
aws s3 ls s3://dynamodb-local-frankfurt/
Download most recent working version with Web Shell:
aws s3 ls s3://dynamodb-local-frankfurt/dynamodb_local_2021-04-27.tar.gz .
The next release of DynamoDB Local will have an updated README indicating its deprecation

As I answered in DynamoDB local http://localhost:8000/shell this appears to be a regression in new versions of DynamoDB Local, where the shell mysteriously stopped working, whereas in versions from a year ago it does work.
Somebody should report it to Amazon. If there is some flag that new versions require you to set to enable the shell, it isn't documented anywhere that I can find.

Update JAVA to the latest version and voila, it works!

Cloudwatch agent not using environment variable credentials on Windows

I'm trying to configure an AMI using a script that installs the unified Cloudwatch agent on both AWS and on premise Windows machines by using static IAM credentials for both of them. As part of the script, I set the credentials statically (as a test) using
$Env:AWS_ACCESS_KEY_ID="myaccesskey"
$Env:AWS_SECRET_ACCESS_KEY="mysecretkey"
$Env:AWS_DEFAULT_REGION="us-east-1"
Once I have the AMI, I create a machine and connect to it, and then verify the credentials are there by running aws configure list
Name Value Type Location
---- ----- ---- --------
profile <not set> None None
access_key ****************C6IF env
secret_key ****************SCnC env
region us-east-1 env ['AWS_REGION', 'AWS_DEFAULT_REGION']
But when I start the agent, I get the following error in the logs.
2022-12-26T17:51:49Z I! First time setting retention for log group test-cloudwatch-agent, update map to avoid setting twice
2022-12-26T17:51:49Z E! Failed to get credential from session: NoCredentialProviders: no valid providers in chain
caused by: EnvAccessKeyNotFound: failed to find credentials in the environment.
SharedCredsLoad: failed to load profile, .
EC2RoleRequestError: no EC2 instance role found
caused by: EC2MetadataError: failed to make EC2Metadata request
I'm using the Administrator user for both the installation of the agent and then when RDPing into the machine. Is there anything I'm missing?
I've already tried adding the credentials to the .aws/credentials file and modifying the common-config.toml file to use a profile. That way it works but in my case I just want to use the environment variables.
EDIT: I tested adding the credentials in the userdata script and modify a bit how they are created and now it seems to work.
$env:aws_access_key_id = "myaccesskeyid"
$env:aws_secret_access_key = "mysecretaccesskey"
[System.Environment]::SetEnvironmentVariable('AWS_ACCESS_KEY_ID',$env:aws_access_key_id,[System.EnvironmentVariableTarget]::Machine)
[System.Environment]::SetEnvironmentVariable('AWS_SECRET_ACCESS_KEY',$env:aws_secret_access_key,[System.EnvironmentVariableTarget]::Machine)
[System.Environment]::SetEnvironmentVariable('AWS_DEFAULT_REGION','us-east-1',[System.EnvironmentVariableTarget]::Machine)
Now the problem is that I'm trying to start the agent at the end of the userdata script with the command from the documentation but it does nothing (I see in the agent logs the command but there is no error). If I RDP into the machine and launch the same command in Powershell it works fine. The command is:
& "C:\Program Files\Amazon\AmazonCloudWatchAgent\amazon-cloudwatch-agent-ctl.ps1" -a fetch-config -m onPrem -s -c file:"C:\ProgramData\Amazon\AmazonCloudWatchAgent\amazon-cloudwatch-agent.json"
I finally was able to make it work but I'm not sure of why it didn't before. I was using
$env:aws_access_key_id = "accesskeyid"
$env:aws_secret_access_key = "secretkeyid"
[System.Environment]::SetEnvironmentVariable('AWS_ACCESS_KEY_ID',$env:aws_access_key_id,[System.EnvironmentVariableTarget]::Machine)
[System.Environment]::SetEnvironmentVariable('AWS_SECRET_ACCESS_KEY',$env:aws_secret_access_key,[System.EnvironmentVariableTarget]::Machine)
[System.Environment]::SetEnvironmentVariable('AWS_DEFAULT_REGION','us-east-1',[System.EnvironmentVariableTarget]::Machine)
to set the variables but then the agent was failing to initialize. I had to add
$env:aws_default_region = "us-east-1"
so it was able to run. I couldn't find the issue before because on Windows server 2022 I don't get the logs from the execution. I had to try using Windows Server 2019 to actually see the error when launching the agent.
I still don't know why the environment variables I set in the machine scope worked once logged into the machine but not when using them as part of the userdata script.

How to make aws cli quiet

When I am using aws cli commands it adds debug data to its output.
Is there a way to make it quiet?
Here is my use case:
# get deployed version
COMMAND="git describe --tags"
aws ecs execute-command --cluster="${CLUSTER}" --task="${TASK}" --container="${SERVICE}" --command="${COMMAND}" --interactive > VERSION
The issue is that instead of expected contents of VERSION file (just the version number):
0.0.67
I have something like that:
The Session Manager plugin was installed successfully. Use the AWS CLI to start a session.
Starting session with SessionId: ecs-execute-command-123456789abcdefgh
0.0.67
Exiting session with sessionId: ecs-execute-command-123456789abcdefgh.
How can I get rid of the debug data?
I already tried adding --quiet parameter (parameter does not exist)
and redirecting error output, none helped.

How do i continue working with Amplify on a new machine?

I'm using react native for my project. On my old machine, when i ran amplify status, i had Auth, Api and Storage services listed.
I moved to my new machine, installed node, watchman, brew etc... and then navigated to my react native project and ran: react-native run-ios, and voila, my app is running. All the calls to my AWS Api, Auth and Storage are working perfectly.
Now i can make some amplify commands. Such as amplify status. I tried: amplify env add: here's what i got:
Users-MBP-2:projectname username$ amplify env add
Note: It is recommended to run this command from the root of your app directory
? Do you want to use an existing environment? Yes
? Choose the environment you would like to use: dev

Do you think credentials info needs to be brought/configured to my new machine?
When i run amplify configure project it's like doing an amplify init and building a project from scratch. I'm being asked:
? Enter a name for the project: ProjectName
? Choose your default editor: Visual Studio Code
? Choose the type of app that you're building javascript
Please tell us about your project
? What javascript framework are you using (Use arrow keys)
angular
ember
ionic
react
❯ react-native
vue
none
etc....
I also already have a region, username and accessKey, secretAccess key etc..
I do not want to replace or ruin anything in my current backend or current project! Whats going on?
Ensure amplify-cli is installed and you're logged in with your AWS details.
npm install -g #aws-amplify/cli
amplify configure
Running amplify configure is mainly to give the cli knowledge of your AWS account so subsequent commands can have access to things.
If you get amplify: command not found errors try restarting your terminal. If still no luck, you will need to check amplify has been added to your PATH variable.
Run amplify env add , but choose an existing environment. This will let you choose the environment you created on your other machine so you can pull those settings down to your new machine.
amplify env add
? Do you want to use an existing environment? Yes
Production
Follow up with:
amplify pull
You don't need to run amplify add auth again or anything. All of that will pull down automatically after you've done the above.
You DO NOT need to do all config again, but some for sure
You have to install amplify cli npm install -g #aws-amplify/cli
use amplify pull
https://docs.amplify.aws/cli/start#amplify-pull
Follow the rest of steps -
-- provide the accessKeyId, secretAccessKey
-- region
-- select amplify project
and then rest of app related thing like IDE, directory......

"puppet agent --test" on client machine aren't getting manifest from the Puppet master server

Issue
So I have two AWS instances: a Puppet master and a Puppet client. When I run sudo puppet agent --test on my client, the tasks defined in my master's manifest didn't apply to the client instance.
Where I am right now
puppetmaster is installed on the master instance
puppet is installed on client instance
Master just finished signing my client's certificate. No errors were displayed
Master has a /etc/puppet/manifests/site.pp
Client's puppet.conf file has a server=dns_of_master line
My Puppet version is 5.4.0. I'm using the default manifest configuration.
Here's the guide that I'm following: https://www.digitalocean.com/community/tutorials/getting-started-with-puppet-code-manifests-and-modules. The only changes are the site.pp content and that I'm using AWS.
If it helps, here's my AWS instances' AMI: ami-06d51e91cea0dac8d
Details
Here's the content on my master's /etc/puppet/manifests/site.pp:
node default {
package { 'nginx':
ensure => installed
}
service { 'nginx':
ensure => running,
require => Package['nginx']
}
file { '/tmp/hello_world':
ensure => present,
content => 'Hello, World!'
}
}
The file has a permission of 777.
Here's the ouput when I run sudo puppet agent --test. This is after I ran sudo puppet agent --enable:
Info: Using configured environment 'production'
Info: Retrieving pluginfacts
Info: Retrieving plugin
Info: Retrieving locales
Info: Caching catalog for my_client_dns
Info: Applying configuration version '1578968015'
Notice: Applied catalog in 0.02 seconds
I have looked at other StackOverflow posts with this issue. I know that my catalog is not getting applied due to the lack of status messages and the quick time. Unfortunately, the solutions didn't apply to my case:
My site.pp is named correctly and in the correct file path /etc/puppet/manifests
I didn't touch my master's puppet.conf file
I tried restarting the server with sudo systemctl but nothing happens
So I have fixed the issue. The guide that I was following required an older version of Ubuntu (16.4, rather than 18.4 as I'm using). This needs a different AMI than the one that I used to create the instances.

Cannot connect to endpoint dynamo db windows 10

I've been following this tutorial (https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DynamoDBLocal.DownloadingAndRunning.html) on how to set up a downloadable DynamoDB on my computer, but have been coming across an issue when I try to connect to a local host.
I have checked my host file and everything seems to be ok...
I am using Windows 10 cmd and these are the outputs on my command line:

Any help will be greatly appreciated!
You must run 'aws configure' and set the required parameters (even if you're only using a local dynamo db emulator, just ignore the access/secret keys)
In addition to running aws configure as mentioned in #J.S.'s answer, you will need to ensure Dynamo DB is running. I recently had this error, where the service had shut down and I didn't realize it. If this is your case, make sure to restart it by going to the folder it is installed in and running java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb &
