Add AWS region me-central-1

Description

We need support for opt in AWS region me-central-1.

Resources:

• endpoint: https://docs.aws.amazon.com/general/latest/gr/ec2-service.html
• country and signature_version: https://docs.aws.amazon.com/general/latest/gr/s3.html

Status

• Done, ready for review.

We tried to follow the documentation (see [1]) to update theses files:

• contrib/scrape-ec2-prices.py
• contrib/scrape-ec2-sizes.py

Sadly when running tox -e scrape-ec2-sizes,scrape-ec2-prices, scrape-ec2-sizes failed:

Afterwards we retried with trunk and its also failing:

  scrape-ec2-sizes: FAIL code -9 (576.78=setup[0.19]+cmd[0.06,576.53] seconds)
  evaluation failed :( (577.21 seconds)

Also the mentioned example (see [2]) in the documentation is outdated. The list EC2_REGIONS does not exist anymore in contrib/scrape-ec2-prices.py.

The change we did seems to be sufficient to delete a VM, are there other tests to run?

Is this PR ready for review or someone can investigate the problem? I also tried running the tox, scrape-ec2-sizes.py downloads a 6GB ec.json file, which looks okay. But this script prints this error.

Using data from existing cached file /tmp/ec.json
scrape-ec2-sizes: exit -9 (837.75 seconds) /opt/libcloud> bash -c 'python contrib/scrape-ec2-sizes.py' pid=28

thanks.

Sorry for the delay. The PR (with somewhat related updates to AWS EC2 sizes and prices) has been merged into trunk.

Thanks for the contribution.
