For a month or so, I've been studying AWS services and now I have to accomplish some basic stuff on AWS elastic beanstalk via command line. As far as I understand there are the aws elasticbeanstalk [command] and the eb [command] CLI installed on the build instance.
When I run eb status inside application folder, I get response in the form:
Environment details for: app-name
Application name: app-name
Region: us-east-1
Deployed Version: app-version
Environment ID: env-name
Platform: 64bit Amazon Linux ........
Tier: WebServer-Standard
CNAME: app-name.elasticbeanstalk.com
Updated: 2016-07-14 .......
Status: Ready
Health: Green
That tells me eb init has been run for the application.
On the other hand if I run:
aws elasticbeanstalk describe-application-versions --application-name app-name --region us-east-1
I get the error:
Unable to locate credentials. You can configure credentials by running "aws configure".
In home folder of current user there is a .aws directory with a credential file containing a [profile] line and aws_access_key_id and
aws_secret_access_key lines all set up.
Beside the obvious problem with the credentials, what I really lack is understanding of the two cli. Why is EB cli not asking for credentials and AWS cli is? When do I use one or the other? Can I use only aws cli? Any clarification on the matter will be highly appreciated.
EDIT:
For anyone ending up here, having the same problem with "Unable to locate credentials". Adding --profile profile-name option solved the problem for me. profile-name can be found in ~/.aws/config (or credentials) file on [profile profile-name] line.
In order to verify that the AWS CLI is configured on your system run aws configure and provide it with all the details it requires. That should fix your credentials problem and checking the change in configuration will allow you to understand what's wrong with your current conf.
the eb cli and the aws cli have very similar capabilities, and I too am a bit confused as to why they both should exist. From my experience the main differences are that the cli is used to interact with your AWS account using simple requests while the eb cli creates connections between you and the eb envs and so allows for finer control over them.
For instance - I've just developed a CI/CD pipeline for our beanstalk apps. When I use the eb cli I can monitor the deployment of our apps and notify the developers when it's finished. aws cli does not offer that functionality, and the only to achieve that is to repeatedly query the service until you receive the desired result.
The AWS CLI is a general tool that works on all AWS resources. It's not tied to a specific software project, the type of machine you're on, the directory you're in, or anything like that. It only needs credentials, whether they've been put there manually if it's your own machine, or generated by AWS if it's an EC2 instance.
The EB CLI is a high level tool to wrangle your software project into place. It's tied to the directory you're in, it assumes that the stuff in your directory is your project, and it has short commands that do a lot of background work to magically put everything in the right place.

I've created an AWS Elastic Beanstalk application and environment. However, I cannot for the life of me figure out how to deploy code to it. Most tutorials I read are for creating a new application directly from the CLI, but I already have one.
I've installed the AWS CLI tools. I created a SSH key-pair to the environment and added it to my .ssh folder. I created an IAM profile and logged in with that in my terminal.
If I understand correctly, I need to do eb use [my environment name] so I can then eb deploy to it. But when I use eb list, nothing comes up. How can I connect to the environment that already exists on AWS?
I am using Linux (WSL on Windows). I'm also on the Free Tier of AWS.
You can either use AWS CLI commands or EB CLI commands to deploy your applications.
Congfigure the source, GIT or S3. e.g. I have uploaded my_app.zip to my_bucket in S3.
Create a new application version. It is a good practise to use commit hash as version label.
aws elasticbeanstalk create-application-version
--application-name <EB_APP_NAME> --version-label <version-label>
--source-bundle S3Bucket="my_bucket",S3Key=my_app.zip --auto-create-application
Update the environment to point to the new application version. The value of version-label should be the same as in the previous step.
aws elasticbeanstalk update-environment
--application-name <EB_APP_NAME>
--environment-name <EB_ENV_NAME>
--version-label <version-label>
The alternative way is to use EB CLI. eb deploy handles all 3 steps above.
Initialize EB CLI using eb init.
Deploy using eb deploy.
I've been using the AWS console to upload a WAR file for deployment. Now I want to do it from the command line. I've been following this guide and see eb init and read the help with eb init --help and eb --help, but the only option is to create a new application.
usage: eb init <application_name> [options ...]
Initializes your directory with the EB CLI. Creates the application.
positional arguments:
application_name application name
How do I link my local source project directory to an existing application in AWS console?
I would expect a command like eb link or something, like how you can just add a Git remote with Heroku and automatically link an existing project to an existing app.
When you perform eb init in the directory containing your source code, eb will prompt you for an application name and an environment name. This way you can link your source code to what ever application/environment is deployed on Beanstalk.
It worked after I got the AWS CLI keys for the project and ran aws configure. I had old keys in ~/.aws/ from a different project from perhaps a decade ago that used a different format. Once I got new keys, that were given permission for these particular apps, and ran aws configure and set the region, then eb init would present a menu of applications to choose from. The command aws elasticbeanstalk describe-applications has to work first before eb can work. I was expecting it would ask for a username and password, like Heroku does.
Install aws and eb command line tools:
Install awscli
Get keys from AWS admin devops.
aws configure (Example Region: 'us-east-1')
aws elasticbeanstalk describe-applications
Install Python
pip install awsebcli --upgrade --user
Add eb to your PATH, probably %USERPROFILE%\AppData\Roaming\Python\Python37\Scripts
eb init
eb list / eb logs / eb ssh / eb status / eb config / eb help
Beanstalk differs from Heroku in this workflow, unless you are using CodeCommit. I am assuming you are just using S3 to store your application versions.
The EBCLI command to do this is:
eb create-application-version
You can specify an application, a version label, as well as either a CodeCommit repository, a codeBuild build, or a source bundle in S3. API docs
You will need to run a separate command before create-application-version to upload to your S3 bucket.
Using the CLI:
aws s3 cp <filename> <s3bucket>
API docs
You can also use the console.
It seems like that guide skips initializing your local git repository. For linking your local source project to beanstalk, make sure you have initialized a local git repository. Then you can link your workspace and application using eb init. more about EB CLI and Git
Based on my understanding, your question is that you had a project directory on your PC and run your app at the localhost, now you want to run it in the AWS Elastic Beanstalk to make it public.
If you have created an EB application in the EB management console and uploaded your bundled source code, the source code becomes an application version, you need to deploy it into one of your environment using the EB management console, like this:
Figure of the management console.
Then the EB platform(container) will take care of that and run your server automatically as long as you set up the command which your app uses to run the server, the proxy, and other configurations either through the EB management console -> [Your environment] -> configuration or using the .ebextensions file.
If everything is well, you can visit your app's home page through the environment URL at that time.
I'm attempting to deploy an app from one ElasticBeanstalk instance to another. Running pip install awsebcli --upgrade --user doesnt install the eb cli tool for some odd reason on the EC2 machine.
Does anyone know the equivalent of eb deploy using only the aws cli options?
This question is a bit confusing. Are you attempting to move code between EC2 instances in your Beanstalk environment?
If I'm assuming correctly, you've pulled/changed your code on one Beanstalk host. And now you're trying to propagate that change to the other instances using the EB CLI. That's not a best practice. Beanstalk has a mechanism to deploy your code to all instances.
The EB CLI is meant to be run from your workstation to push code from your IDE/editor to the Beanstalk hosts in AWS.
Beanstalk keeps a copy of that code revision in S3. And if the Beanstalk environment is load balanced then all instances will be running the same application version when scaling events or deployments occur because it will pull your code from a common source.
But to answer your question:
Does anyone know the equivalent of eb deploy using only the aws cli options?
You're gonna wanna ZIP and upload your code to S3 and note the S3 key and bucket values of where it's located.
Then create a new application version.
% aws elasticbeanstalk create-application-version --application-name="<APPLICATION_NAME>" --version-label="<NEW_VERSION_LABEL>" --source-bundle="{\"S3Bucket\": \"<S3_BUCKET_NAME>\",\"S3Key\": \"<S3_KEY>\"}"
Then deploy your new application version to the running environment.
% aws elasticbeanstalk update-environment --environment-id="<ENVIRONMENT_ID>" --version-label="<NEW_VERSION_LABEL>"
Reading is hard...
Linux requires you to "[a]dd the path to the executable file to your PATH variable"
export PATH=~/.local/bin:$PATH
eb --version now works
I have deployed an application on EB with my own AWS account, and have done the same with another one.
I don't know how to switch out of my command line eb cli account. There are no eb CLI options to switch profiles like the normal AWS CLI...
Thanks!
Use named profiles via eb --profile x to use a specific profile from your AWS credentials file.
Or you can use multiple, distinct credentials files (see here) and change the AWS_CREDENTIAL_FILE environment variable to point to the relevant credentials file. You could even write a couple of shell scripts such as eb-project1 and eb-project2 that each export/set the relevant AWS_CREDENTIAL_FILE value and then simply execute eb so that you don't have to switch credentials manually - just run eb-project1 or eb-project2 as needed instead of running eb.
I have two AWS accounts, one for personal, one for work-related projects. I've previously created and deployed to my personal AWS account.
I want to create a work-related app on the work AWS account. I signed in with those credentials, and created a new application from within the console.
Then, in my work project folder, I eb init and eb create/deploy the work app. When I did eb create, it was asking to set up a an environment different than the one I had created in AWS. After creating it, I found that a new project had be created within my personal AWS account.
I was told I have to change profiles doing eb --profile but am not sure of my profile names. How can I list and change my profile from my personal to my work profile?
EDIT:
I was given an access key ID. I tried eb --profile MYKEYID. No message was displayed when I did this. I'm not sure which profile I'm on.
The EB CLI and the AWS CLI share the same credentials.
They are stored in either ~/.aws/config or ~/.aws/credentials.
You can list them using
aws configure list
Once you know what profile you want to use, you can set it permanently for that project by running
eb init --profile ProfileName
in the project directory.
You can see what settings the EB CLI has for your project by looking at the .elasticbeanstalk/config.yml file.
