Cómo conectarse a AWS ECR mediante Python Docker-Py

Solución 1:

Ejemplo de código de trabajo completo:

#!/usr/bin/env python3
import base64, docker, boto3

docker_client = docker.from_env(version='1.24')
ecr_client = boto3.client('ecr', region_name='eu-west-1')

token = ecr_client.get_authorization_token()
username, password = base64.b64decode(token['authorizationData'][0]['authorizationToken']).decode().split(':')
registry = token['authorizationData'][0]['proxyEndpoint']

docker_client.login(username, password, registry=registry)

Y, por supuesto, primero debe configurar sus credenciales de AWS, por ejemplo:

export AWS_ACCESS_KEY_ID=youraccesskey
export AWS_SECRET_ACCESS_KEY=yoursecretaccesskey

Solucion 2:

Estaba enfrentando el mismo problema, tienes que:

decodificar desde base64

conversión de byte a cadena

segregar las credenciales de 'AWS'

 password = (base64.b64decode(response['authorizationData'][0]['authorizationToken'])).decode("utf-8").split(':')[-1]

Solución 3:

error de inicio de sesion

dockerClient se niega a conectarse con un "nombre de usuario o contraseña no válidos"

La firma de la función a la que está llamando para iniciar sesión es:

def login(self, username, password=None, email=None, registry=None,
          reauth=False, insecure_registry=False, dockercfg_path=None):

Tenga en cuenta la posición del registryparámetro. Ocupa el cuarto lugar en la lista. Entonces tu llamado para:

regClient = dockerClient.login(username, password, registry)

Su paso registryes emaildesde como emailtercer parámetro. Sugiero que cambie a algo como:

regClient = dockerClient.login(username, password, registry=registry)

¿Python o shell?

¿Es la dirección correcta o debería intentar hacer esto únicamente con scripts de shell? (Python es especialmente valioso para las llamadas de boto para describir lo que hay en cada registro)

Ve con Python.

Python Tricks Every Developer Should Know

Python is awesome, it’s one of the easiest languages with simple and intuitive syntax but wait, have you ever thought that there might ways to write your python code simpler?

In this tutorial, you’re going to learn a variety of Python tricks that you can use to write your Python code in a more readable and efficient way like a pro.

Let’s get started

Swapping value in Python

Instead of creating a temporary variable to hold the value of the one while swapping, you can do this instead

>>> FirstName = "kalebu"
>>> LastName = "Jordan"
>>> FirstName, LastName = LastName, FirstName 
>>> print(FirstName, LastName)
('Jordan', 'kalebu')

How to Remove all Duplicate Files on your Drive via Python

Today you’re going to learn how to use Python programming in a way that can ultimately save a lot of space on your drive by removing all the duplicates.


In many situations you may find yourself having duplicates files on your disk and but when it comes to tracking and checking them manually it can tedious.

Heres a solution

Instead of tracking throughout your disk to see if there is a duplicate, you can automate the process using coding, by writing a program to recursively track through the disk and remove all the found duplicates and that’s what this article is about.

But How do we do it?

If we were to read the whole file and then compare it to the rest of the files recursively through the given directory it will take a very long time, then how do we do it?

The answer is hashing, with hashing can generate a given string of letters and numbers which act as the identity of a given file and if we find any other file with the same identity we gonna delete it.

There’s a variety of hashing algorithms out there such as

  • md5
  • sha1
  • sha224, sha256, sha384 and sha512

Serverless Containers With AWS Fargate and Docker

In AWS there are a few services which seem similar or related when it comes to containerisation. They do have their nuances so let’s begin with an introduction of what these are and their similarities and differences (according to the AWS documentation)

Elastic Container Service (ECS)

  • Fully managed container orchestration service
  • Manages the lifecycle and placement of tasks comprised of one or more containers that work together
  • Does not run or execute your container(s)
  • Containers run using ECS Container Instances (normal EC2 instances with ECS Container Agent) or Fargate
  • ECS Container Agent regularly polls the ECS API to manage state
  • Cluster of container instances run in an auto-scaling group
  • You** manage your own EC2 instance, patching and scaling**
  • ECS is free but pricing is per running EC2 instance
  • Offers integration with Elastic Load Balancing (ELB)
  • Supports Application Load Balancer (ALB), the Network Load Balancer (NLB) and Classic Load Balancer (CLB)
  • Load balancing is efficient
  • Each task has its own Elastic Network Interface (ENI)
  • Supports IAM roles for tasks
  • AWS proprietary
