cdpcurl 1.0.0

A curl-like tool for Cloudera on Cloud (CDP) API requests

cdpcurl

curl-like tool with CDP request signing. Inspired by and built from awscurl. See that repository's README for installation and usage instructions beyond what is provided here.

Building

Create a virtualenv if desired.

# For typical virtualenv
virtualenv cdpcurlenv
cdpcurlenv/bin/activate

# For pyenv
pyenv virtualenv cdpcurlenv
pyenv activate cdpcurlenv

Then, in this directory:

pip install .

Usage

Run cdpcurl --help for a complete list of options.

Before using cdpcurl, generate an access key / private key pair for your CDP user account using the CDP management console. You have two options for passing those keys to cdpcurl:

• Pass the keys to cdpcurl using the --access-key and --private-key options
• (Recommended) Create a profile in $HOME/.cdp/credentials containing the keys and then use the --profile option in cdpcurl calls

For example:

[myuserprofile]
cdp_access_key_id = 6744f22e-c46a-406d-ad28-987584f45351
cdp_private_key = abcdefgh...................................=

Most CDP API calls are POST requests, so be sure to specify -X POST, and provide the request content using the -d option. If the -d option value begins with "@", the remainder of the value is the path to a file containing the content; otherwise, the value is the content itself.

To form the URI, start by determining the hostname based on the service being called:

• iam: iamapi.us-west-1.altus.cloudera.com
• all other services: api.us-west-1.cdp.cloudera.com

The correct URI is an HTTPS URL at the chosen host, with a path indicated for your desired endpoint in the API documentation.

Examples

Get your own account information, using a profile named demo:

$ cdpcurl --profile demo -X POST -d '{}' https://iamapi.us-west-1.altus.cloudera.com/iam/getAccount

List all environments with the sandbox profile:

$ cdpcurl --profile sandbox -X POST -d '{}' https://api.us-west-1.cdp.cloudera.com/api/v1/environments2/listEnvironments

Request Signing

A CDP API call requires a request signature to be passed in the x-altus-auth header, along with a corresponding timestamp in the x-altus-date" header. cdpcurl constructs the headers automatically. However, if you would rather use a different HTTP client, such as ordinary curl, then you may directly use the cdpsign script within cdpcurl to generate these required headers. You may then parse the header values from the script output and feed them to your preferred client.

[!warning] CDP API services will reject calls with timestamps too far in the past, so generate new headers for each call.

$ cdpsign -X POST https://api.us-west-1.cdp.cloudera.com/api/v1/environments2/listEnvironments
Content-Type: application/json
x-altus-date: Fri, 28 Aug 2020 20:38:38 GMT
x-altus-auth: (very long string value)

The signature algorithm specification is available from the API documentation.
