Mock for AWS API.
- It developed and tested on Debian-like OSes only
- You need Docker to build and run the server
- You need OpenSSL'
opensslbinary and GNUsedfor scripts
$ docker build -t aws_mock .
- Make sure you have Python 3.10
- Install Poetry
- Install the Python requirements using poetry:
$ poetry install
The AWS Mock server use AWS_MOCK_HOSTS environment variable as a space-separated list of hosts:
$ export AWS_MOCK_HOSTS="ec2.eu-north-1.amazonaws.com my-bucket.s3.amazonaws.com"
$ scripts/run.sh
Default Docker container name is aws_mock but you can provide it using --name option of the script.
$ mkdir ./.aws_mock_ca
$ scripts/run.sh --ca-files ./.aws_mock_ca
This command will generate all required keys and certificates on the first run and store them to
./.aws_mock_ca directory. On consequent runs it'll reuse CA files but regenerate server key and certificate.
$ scripts/run.sh --dev
This command will map local aws_mock to the Docker container and publish port 443 to localhost.
Also, it'll monitor for source files and restart uWSGI on changes.
You can combine both --ca-files and --dev options together.
$ scripts/mocked-hosts.sh --patch-etc-hosts
This command will extract hosts from the AWS mock server SSL certificate and add them to /etc/hosts file.
By default, it uses 127.0.0.1 as IP address, and it's OK if you run Docker container in development mode, but
you can specify any IP address using --ip option if port 443 not published to the localhost:
$ scripts/mocked-hosts.sh --patch-etc-hosts --ip 172.17.0.2
or get IP address from a Docker container via --container option:
$ scripts/mocked-hosts.sh --patch-etc-hosts --container aws_mock
$ curl -k https://aws-mock.itself/install-ca.sh | bash
This command will add AWS Mock CA certificate to /usr/local/share/ca-certificates and to the certifi's CA bundle
in current Python environment.
Note, that it assumes you use a Debian-like Linux distribution and have already patched /etc/hosts.
⚠️ Note, it's supposed to run on a Debian-like OS.
Build and run the AWS Mock server:
$ docker build -t aws_mock .
$ mkdir ./.aws_mock_ca
$ export AWS_MOCK_HOSTS="ec2.eu-north-1.amazonaws.com my-bucket.s3.amazonaws.com"
$ scripts/run.sh --ca-files ./.aws_mock_ca --dev
In another terminal:
$ scripts/mocked-hosts.sh --patch-etc-hosts
$ curl -k https://aws-mock.itself/install-ca.sh | bash
$ docker exec aws_mock bash -c 'mkdir /src/s3/my-bucket; echo Hello > /src/s3/my-bucket/hello'
