AWS Lambda
Connecting AWS Lambda account to CodeMash
The following steps show how to connect the AWS Lambda account to CodeMash. The steps consist of:
Creating an AWS account.
Adding function execution role (attaching to functions).
Adding function invocation role (attaching to API user).
Connecting account into the CodeMash project.
Creating AWS account
If you already have an AWS account, skip this section.
Go to https://aws.amazon.com/lambda/ and create an AWS account.
After you create your account, log in to the AWS management console.
Creating the first function
If you already have your functions ready, skip this section.
From the management console, select Services from the menu bar and search for Lambda.
In the opened functions list, press Create function.
Here select Author from scratch set any Function name and select Runtime. Below expand the Permissions section. Here you need to select a role with which to execute a function. Preferably you want to select a Use an existing role option and create a role that you can later apply to your other functions. To create a new role, press the IAM console link provided near the options.
Creating a role. The following steps lead to the role creation process.
For Select type of trusted entity select AWS service. For use case, select Lambda.
For permission, at least select the AWSLambdaBasicExecutionRole policy. This will allow you to execute your function. You can select other policies, like AWSLambdaExecute which would allow access to S3 service.
Finish role creation.
Now back in function creation page, refresh existing roles, and select your created role.
Adding API user
If you already have your user with access and secret keys, skip this section.
From the management console, select Services from the menu bar and search for IAM.
In the IAM management console, open the Users tab and press Add User.
The following steps lead to user creation.
Step 1. For username set any username you like, for example, codemash_api. For Access type select Programmatic access.
Step 2. Set permission. You can create a group or attach existing policies directly. The policies that you want to attach are - AWSLambdaReadOnlyAccess and AWSLambdaRole. That allows us to get your functions and save them in your CodeMash project. The second role allows us to invoke your function from CodeMash.
The following step (tags) are optional and not used by CodeMash.
After the user has been successfully created, you will get its credentials - access key and secret key. Copy these. You can add more keys later from the user dashboard.
Adding API credentials to CodeMash
Once you have a user to invoke your functions, use it's access key and secret key when adding an AWS Lambda account in CodeMash.
To get the keys, go to the IAM management console (image above Selecting IAM service), open the Users tab, and select your user with programmatic access. Make sure, that your user has AWSLambdaReadOnlyAccess and AWSLambdaRole permissions.
Open Security credentials tab. Hereunder Access keys create new access key if you don't have valid access, secret key pair.
Now go to CodeMash project dashboard and navigate to Code > Account > Add New > AWS Lambda.
Fill the fields. Example with filled details shown below.
Access Key - your API user access key.
Secret Key - your API user secret key.
Region - all the regions from which you want to get your functions.
Refresh Settings - in case you are developing your functions and don't want to refresh them manually (to show up in CodeMash), you can automatically refresh at certain intervals.
Tags - function tags. Only those functions that have at least 1 of the tag will be imported into CodeMash. If no tags are added, then all functions will be imported.
After connecting, your functions will appear in the functions tab. This process might take a few moments to receive all functions from AWS services.
