SCRU128 ID is yet another attempt to supersede UUID for the users who need decentralized, globally unique time-ordered identifiers. SCRU128 is inspired by ULID and KSUID and has the following features:

• 128-bit unsigned integer type
• Sortable by generation time (as integer and as text)
• 25-digit case-insensitive textual representation (Base36)
• 48-bit millisecond Unix timestamp that ensures useful life until year 10889
• Up to 281 trillion time-ordered but unpredictable unique IDs per millisecond
• 80-bit three-layer randomness for global uniqueness

#include "scru128.h"

#include <stdio.h>

int main() {
  Scru128Generator g;
  scru128_generator_init(&g);

  // generate a new identifier
  uint8_t x[16];
  scru128_generate(&g, x);
  char text[SCRU128_STR_LEN]; // 26 bytes
  scru128_to_str(x, text);
  puts(text); // e.g., "036z951mhjikzik2gsl81gr7l"

  // generate a textual representation directly
  scru128_generate_string(&g, text);
  puts(text); // e.g., "036z951mhzx67t63mq9xe6q0j"

  return 0;
}

See SCRU128 Specification for details.

scru128.h does not provide a concrete implementation of scru128_generate(), so users have to implement it to enable high-level generator APIs (if necessary) by integrating the low-level generator primitives provided by the library with the real-time clock and random number generator available in the system. Here is a quick example for the BSD-like systems:

#include "scru128.h"

#include <stdlib.h> // or <bsd/stdlib.h> on Linux with libbsd
#include <time.h>

int scru128_generate(Scru128Generator *g, uint8_t *id_out) {
  struct timespec tp;
  int err = clock_gettime(CLOCK_REALTIME, &tp);
  if (err) {
    return SCRU128_GENERATOR_STATUS_ERROR;
  }
  uint64_t timestamp = (uint64_t)tp.tv_sec * 1000 + tp.tv_nsec / 1000000;
  return scru128_generate_or_reset_core(g, id_out, timestamp, &arc4random,
                                        10000);
}

This Python script simulates the operation of an Enigma machine, a type of encryption device used by the Germans during World War II. The script allows the user to input the settings for the rotors, reflector, and plugboard (appairages), and then it simulates the operation of the machine based on these settings.

Run the script. You will be prompted to enter the settings for the rotors, reflector, and plugboard.

1. Input the rotors as ‘Y-X’ where Y is the rotor number and X is the value. You need to input three rotors. For example: 1-1 3-2 5-6.

2. Input the plugboard settings (appairages) as ‘A-C’. You can input up to 10 pairs. For example: A-B C-D E-F G-H I-J K-L M-N O-P Q-R S-T.

3. Input the reflector as a single letter: A, B, or C.

4. If the input is valid, the script will continue to the main function. If the input is invalid, the script will print “Invalid Input” and exit.

Input rotors comme ça 'Y-X' Avec Y le rotor et X la valeure (*3) et les appairages comme ça 'A-C' (*10) et le reflecteur : A ou B ou C
Espace = clear et Entrée = quitter
Rotors: 1-1 3-2 5-6
[1, 1, 3, 2, 5, 6]
appairage: A-B C-D E-F G-H I-J K-L M-N O-P Q-R S-T
['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T']
Reflecteur: B
B

This script is a simulation and does not provide real encryption. It is intended for educational purposes only.

conu is a library which makes it easy to write tests for your containers and is handy when playing with containers inside your code. It defines an API to access and manipulate containers, images and provides more, very helpful functions.

conu is supported on python 3.6+ only.

conu is available on PyPI, so you can easily install it with pip:

$ pip install --user conu

If you are running Fedora, we have packaged conu in an RPM:

$ dnf install python3-conu

Please visit our documentation for more info on installation.

You can try conu also in the container, but you have to:

• mount docker socket
• use --cap-add SYS_ADMIN for mounting containers/images
• set --privileged option or turn off the SELinux to allow access to docker inside the container:

docker run -it --rm \
-v /var/run/docker.sock:/var/run/docker.sock:z \
--cap-add SYS_ADMIN \
--privileged \
usercont/conu:0.6.0 python3

>>> from conu import DockerBackend
>>> backend = DockerBackend()
11:52:13.022 backend.py        INFO   conu has initiated, welcome to the party!
>>> image = backend.ImageClass('docker.io/library/nginx')
11:52:32.562 __init__.py       INFO   docker environment info: ...
>>> container = image.run_via_binary()
11:52:51.910 image.py          INFO   run container via binary in background

If you want to run custom source file, mount it to the container in the following way:

docker run -it --rm \
-v /var/run/docker.sock:/var/run/docker.sock:z \
-v $PWD/my_source.py:/app/my_source.py:z \
--cap-add SYS_ADMIN \
--privileged \
usercont/conu:0.6.0 python3 /app/my_source.py

• load, pull, mount and remove container images
• obtain low-level image metadata
• check presence of files and directories inside a container image
• read files inside an image
• get selinux context of files in an image
• extend image using s2i
• check all packages in image are signed with a key
• run image inside Kubernetes pod

• kill, get logs, exec a command, mount, remove, start, stop, wait, run – via api or via binary
• get low-level container metadata
• shortcut methods for getting:
  • IPv4 and IPv6 addresses
  • PID of root process in the container
  • port mappings
  • container status
• HTTP requests support
• open a TCP connection with the service inside container
• perform checks whether
  • the container is running
  • mapped ports are opened

• easily create and delete a directory and set its options:
  • mode
  • ownership
  • selinux context
  • access control lists (facl)
• port availability check
• check SELinux status on host
• run a command on host
• easy random string generation
• support for probes (execute a function in a separate process):
  • repeat until a condition is met
  • repeat N times
  • delay execution
  • delay between iterations

• create/delete new namespace
• create/delete Pod
• create/delete Deployment
  • with parameters
  • from template
• create/delete Service
• shortcut methods for getting:
  • pod logs
  • pod IP
  • pod phase
  • pod condition
  • service IP
• perform checks whether
  • pod is ready
  • all pods are ready for specific deployment

• create new app using oc new-app command
  • deploy pure image into openshift
  • support building s2i images from remote repository
  • support building s2i images from local path
  • support creating new applications using OpenShift templates
• push images to internal OpenShift registry
• request service
• waiting until service is ready
• obtain logs from all pods
• get status of application
• check readiness of pods
• cleanup objects of specific application in current namespace

Let’s look at a practical example:

$ cat examples/readme_webserver.py

#!/usr/bin/python3

import logging

from conu import DockerRunBuilder, DockerBackend

# our webserver will be accessible on this port
port = 8765

# we'll utilize this container image
image_name = "registry.fedoraproject.org/fedora"
image_tag = "27"

# we'll run our container using docker engine
with DockerBackend(logging_level=logging.DEBUG) as backend:
    # the image will be pulled if it's not present
    image = backend.ImageClass(image_name, tag=image_tag)

    # the command to run in a container
    command = ["python3", "-m", "http.server", "--bind", "0.0.0.0", "%d" % port]
    # let's run the container (in the background)
    container = image.run_via_binary(command=command)
    try:
        # we need to wait for the webserver to start serving
        container.wait_for_port(port)
        # GET on /
        # this is standard `requests.Response`
        http_response = container.http_request(path="https://github.com/", port=port)
        assert http_response.ok
        assert '<a href="https://github.com/user-cont/etc/">etc/</a>' in http_response.content.decode("utf-8")
        # let's access /etc/passwd
        etc_passwd = container.http_request(path="/etc/passwd", port=port).content.decode("utf-8")
        assert 'root:x:0:0:root:/root:' in etc_passwd
        # we can also access it directly on disk and compare
        with container.mount() as fs:
            assert etc_passwd == fs.read_file("/etc/passwd")
    finally:
        container.kill()
        container.delete()

Let’s run it and look at the logs:

The test passed! The logs should be easy to read, so you should have pretty good overview of what happened.

If you want to test your images in Kubernetes locally, you will need to run kubernetes cluster on your host. We recommend to use minikube, for installation follow instructions in minikube github repository.

After that, run minikube like this:

$ minikube start

$ cat examples/k8s_deployment.py

from conu.backend.k8s.backend import K8sBackend
from conu.backend.k8s.deployment import Deployment
from conu.utils import get_oc_api_token

# obtain API key from OpenShift cluster. If you are not using OpenShift cluster for kubernetes tests
# you need to replace `get_oc_api_token()` with your Bearer token. More information here:
# https://kubernetes.io/docs/reference/access-authn-authz/authentication/
api_key = get_oc_api_token()

with K8sBackend(api_key=api_key) as k8s_backend:

    namespace = k8s_backend.create_namespace()

    template = """
    apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: hello-world
      labels:
        app: hello-world
    spec:
      replicas: 3
      selector:
        matchLabels:

      template:

          labels:
            app: hello-world
        spec:
          containers:
          - name: hello-openshift
            image: openshift/hello-openshift
    """

    test_deployment = Deployment(namespace=namespace, from_template=template,
                                 create_in_cluster=True)

    try:
        test_deployment.wait(200)
        assert test_deployment.all_pods_ready()
    finally:
        test_deployment.delete()
        k8s_backend.delete_namespace(namespace)

Let’s run it and look at the logs:

$ python3 examples/k8s_deployment.py

13:23:09.479 backend.py        INFO   conu has initiated, welcome to the party!

If you want to test your images in OpenShift locally, you need to run OpenShift cluster on your host. You can install it by following instructions in OpenShift origin or minishift github repositories.

After that, you may need to setup cluster, here is example setup:

oc cluster up
oc login -u system:admin
oadm policy add-role-to-user system:registry developer
oadm policy add-role-to-user admin developer
oadm policy add-role-to-user system:image-builder developer
oadm policy add-cluster-role-to-user cluster-reader developer
oadm policy add-cluster-role-to-user admin developer
oadm policy add-cluster-role-to-user cluster-admin developer
oc login -u developer -p developer

For more information, why do you need to grant all these rights to user see accessing registry
