You may want to connect your Posit Workbench session to an S3 bucket to pull data from Amazon Web Services (AWS). It's worth mentioning that this topic falls outside of our support SLA! That said, we have seen success with the method used below.
Connecting to S3
There is an open-source package that allows you to connect your R session to the S3 API. It's worth noting that this package isn't supported, maintained, or endorsed by Posit or Amazon. However, it is useful when connecting your R session to AWS S3.
To install the package, you can run the following command in the R terminal:
From there, we can use this library within our session:
Once complete, we need to ensure that we have associated our appropriate RBAC (role-based access control) account to our R session. To do so, you can set the following variables within your environment using the R terminal:
"AWS_ACCESS_KEY_ID" = "0000000",
"AWS_DEFAULT_REGION" = "us-west-2",
"AWS_SESSION_TOKEN" = "0000000")
Note that the zeros used in the above are simply placeholders. You will need to replace the values within the quotation marks with the values that correspond to your AWS account. The region used is also a placeholder, you will need to change this if it is different to Oregon (us-west-2).
A solution to using an IAM role may be to use the
aws.ec2metadata packages. This package pulls EC2 instance metadata from within the running instance.
You will first need to install the
aws.ec2metadata packages. You can do so as below:
Sys.setenv("AWS_DEFAULT_REGION" = 'us-east-1')
In the code block above,
us-east-1 is an example - you will need to change this value to suit your S3 environment.
Once you've run the commands above, you can begin pulling data from S3! You can start by listing your buckets using the command below:
