Question 1

How do I use Erlcloud with AWS temporary credentials?

Accepted Answer

Set environment variables like AWS_ACCESS_KEY_ID, or use erlcloud_aws:profile() to read from AWS profiles, as explained in the README for temporary security credentials. You can also configure via application environment variables for flexibility.

Question 2

Is Erlcloud compatible with Elixir projects?

Accepted Answer

Yes, since it's an Erlang library available on Hex.pm, it can be used in Elixir via Mix dependencies. However, configuration may need adaptation to Elixir's syntax and conventions.

Question 3

Erlcloud or aws-sdk-erlang: which is better for Erlang?

Accepted Answer

Erlcloud has broader historical service coverage and follows Erlang idioms closely, while aws-sdk-erlang might offer more official AWS alignment but less maturity. Choose Erlcloud for extensive, community-vetted integration, but check for specific API needs.

Question 4

How to handle pagination in Erlcloud S3 operations?

Accepted Answer

Erlcloud uses markers or tokens in responses; for example, list_buckets can return paginated results with configuration options. Refer to the source code and AWS documentation for details, as the README mentions best practices for paging logic.

Question 5

What Erlang versions does Erlcloud support?

Accepted Answer

It supports OTP releases from 19.3 to 27.1, as tested with eunit and dialyzer, but active use varies, so verify the supported list in the README and report issues for older versions.

Question 6

Does Erlcloud support all S3 API features?

Accepted Answer

While it covers common S3 operations, the README notes that not all functions are thoroughly tested and functionality may be missing compared to aws-cli. Check the source code for specific feature implementation.

Question 7

How to contribute or request new features in Erlcloud?

Accepted Answer

Submit issues or patches via GitHub, as the project adds functionality upon request. Follow the indentation and best practices guidelines in the README for contributions.
