QUESTION
Python/Docker ImportError: cannot import name 'json' from itsdangerous
Asked 2022-Mar-31 at 12:49I am trying to get a Flask and Docker application to work but when I try and run it using my docker-compose up command in my Visual Studio terminal, it gives me an ImportError called ImportError: cannot import name 'json' from itsdangerous. I have tried to look for possible solutions to this problem but as of right now there are not many on here or anywhere else. The only two solutions I could find are to change the current installation of MarkupSafe and itsdangerous to a higher version: https://serverfault.com/questions/1094062/from-itsdangerous-import-json-as-json-importerror-cannot-import-name-json-fr and another one on GitHub that tells me to essentially change the MarkUpSafe and itsdangerous installation again https://github.com/aws/aws-sam-cli/issues/3661, I have also tried to make a virtual environment named veganetworkscriptenv to install the packages but that has also failed as well. I am currently using Flask 2.0.0 and Docker 5.0.0 and the error occurs on line eight in vegamain.py.
Here is the full ImportError that I get when I try and run the program:

ANSWER
Answered 2022-Feb-20 at 12:31I was facing the same issue while running docker containers with flask.
I downgraded Flask to 1.1.4 and markupsafe to 2.0.1 which solved my issue.
Check this for reference.
QUESTION
Docker push to AWS ECR hangs immediately and times out
Asked 2022-Mar-30 at 07:53I'm trying to push my first docker image to ECR. I've followed the steps provided by AWS and things seem to be going smoothly until the final push which immediately times out. Specifically, I pass my aws ecr credentials to docker and get a "login succeeded" message. I then tag the image which also works. pushing to the ecr repo I get no error message, just the following:
1The push refers to repository [xxxxxxxxxxx.dkr.ecr.ca-central-1.amazonaws.com/reponame]

13It tries a bunch of times and then exits with no message. Any idea what's wrong?
ANSWER
Answered 2022-Jan-02 at 14:23I figured out my issue. I wasn't using the correct credentials. I had a personal AWS account as my default credentials and needed to add my work profile to my credentials.
EDIT
If you have multiple aws profiles, you can mention the profile name at the docker login as below (assuming you have done aws configure --profile someprofile at earlier day),

EmbeddedKafka failing since Spring Boot 2.6.X : AccessDeniedException: ..\AppData\Local\Temp\spring.kafka*
Asked 2022-Mar-25 at 12:39e: this has been fixed through Spring Boot 2.6.5 (see https://github.com/spring-projects/spring-boot/issues/30243)
Since upgrading to Spring Boot 2.6.X (in my case: 2.6.1), I have multiple projects that now have failing unit-tests on Windows that cannot start EmbeddedKafka, that do run with Linux
There is multiple errors, but this is the first one thrown

72I do not have this error when pinning kafka.version to 2.8.1 in pom.xml's properties.
It seems like the cause is in Kafka itself, but I have a hard time figuring out if it is spring-kafka intitializing Kafka via EmbeddedKafka incorrectly or if Kafka itself is the culrit here.
Anyone has an idea? Am I missing a test-parameter to set?
ANSWER
Answered 2021-Dec-09 at 15:51Known bug on the Apache Kafka side. Nothing to do from Spring perspective. See more info here: https://github.com/spring-projects/spring-kafka/discussions/2027. And here: https://issues.apache.org/jira/browse/KAFKA-13391
You need to wait until Apache Kafka 3.0.1 or don't use embedded Kafka and just rely on the Testcontainers, for example, or fully external Apache Kafka broker.

dlopen: libcrypt.so.1: cannot open shared object file: No such file or directory
Asked 2022-Mar-13 at 10:37I use EndevourOS and have updated my system on February 17 2022 using
sudo pacman -Syu
Eversince, when I run docker-compose, I get this error message:
[4221] Error loading Python lib '/tmp/_MEIgGJQGW/libpython3.7m.so.1.0': dlopen: libcrypt.so.1: cannot open shared object file: No such file or directory
Some forum threads suggested to reinstall docker-compose, which I did. I tried following solution. But both without success: Python3.7: error while loading shared libraries: libpython3.7m.so.1.0
How can I resolve this issue?
ANSWER
Answered 2022-Feb-19 at 22:27I found several forum posts explaining to isntall libxcrypt-compat from AUR. I did not like this solution, but apparently, this is the way for now: https://bbs.archlinux.org/viewtopic.php?id=274160&p=2
If there is a PGP key error when building the package from AUR, use this workaround as explained by Stock44 on this page: https://aur.archlinux.org/packages/libxcrypt-compat

QUESTION
WARNING: Running pip as the 'root' user
Asked 2022-Feb-24 at 01:59I am making simple image of my python Django app in Docker. But at the end of the building container it throws next warning (I am building it on Ubuntu 20.04):
1WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead
2Why does it throw this warning if I am installing Python requirements inside my image? I am building my image using:
1WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead
2sudo docker build -t my_app:1 .
3Should I be worried about warning that pip throws, because I know it can break my system?
Here is my Dockerfile:
1WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead

14ANSWER
Answered 2021-Aug-29 at 08:12The way your container is built doesn't add a user, so everything is done as root.
You could create a user and install to that users's home directory by doing something like this;

332QUESTION
Create a Linux-based Docker file for .NET Framework project
Asked 2022-Jan-27 at 18:27I have an ASP.Net Framework 4.8 project. I want to create a Linux-based Docker file for this project, but I can't find a Linux-based image to use as a base image in my Docker file for .NET Framework. How can I create a Docker file for this?
ANSWER
Answered 2022-Jan-27 at 14:42.NET Framework is not cross-platform. Neither is ASP.NET itself. They do not work on Linux. So there are no Linux-based container images that would let you run .NET Framework or ASP.NET Framework.
And you can not make a custom one; .NET Framework will simply not run on Linux.
That's why Microsoft created .NET Core (and now just called .NET) and ASP.NET Core, so they would be cross-platform and you could use those on Linux, including Linux-based container images.
As suggested in some comments, you might be able to use mono. Mono is a (not really supported) implementation of .NET Framework that aims to work on Linux. It's not 100% bug for bug compatible with .NET Framework, so your application may or may not work with it.
A better, but more difficult option, would be to port your application to ASP.NET Core 6, which is supported on Linux-based containers.
QUESTION
Does docker-compose support init container?
Asked 2022-Jan-25 at 09:32init container is a great feature in Kubernetes and I wonder whether docker-compose supports it? it allows me to run some command before launch the main application.
I come cross this PR https://github.com/docker/compose-cli/issues/1499 which mentions to support init container. But I can't find related doc in their reference.
ANSWER
Answered 2021-Dec-21 at 14:11This was a discovery for me but yes, it is now possible to use init containers with docker-compose since version 1.29 as can be seen in the PR you linked in your question.
Meanwhile, while I write those lines, it seems that this feature has not yet found its way to the documentation
You can define a dependency on an other container with a condition being basically "when that other container has successfully finished its job". This leaves the room to define containers running any kind of script and exit when they are done before an other dependent container is launched.
To illustrate, I crafted an example with a pretty common scenario: spin up a db container, make sure the db is up and initialize its data prior to launching the application container.
Note: initializing the db (at least as far as the official mysql image is concerned) does not require an init container so this example is more an illustration than a rock solid typical workflow.
The complete example is available in a public github repo so I will only show the key points in this answer.
Let's start with the compose file
1---
2x-common-env: &cenv
3 MYSQL_ROOT_PASSWORD: totopipobingo
4
5services:
6 db:
7 image: mysql:8.0
8 command: --default-authentication-plugin=mysql_native_password
9 environment:
10 <<: *cenv
11 init-db:
12 image: mysql:8.0
13 command: /initproject.sh
14 environment:
15 <<: *cenv
16 volumes:
17 - ./initproject.sh:/initproject.sh
18 depends_on:
19 db:
20 condition: service_started
21 my_app:
22 build:
23 context: ./php
24 environment:
25 <<: *cenv
26 volumes:
27 - ./index.php:/var/www/html/index.php
28 ports:
29 - 9999:80
30 depends_on:
31 init-db:
32 condition: service_completed_successfully
33You can see I define 3 services:
- The database which is the first to start
- The init container which starts only once db is started. This one only runs a script (see below) that will exit once everything is initialized
- The application container which will only start once the init container has successfuly done its job.
The initproject.sh script run by the db-init container is very basic for this demo and simply retries to connect to the db every 2 seconds until it succeeds or reaches a limit of 50 tries, then creates a db/table and insert some data:

30 depends_on:
31 init-db:
32 condition: service_completed_successfully
33#! /usr/bin/env bash
34
35# Test we can access the db container allowing for start
36for i in {1..50}; do mysql -u root -p${MYSQL_ROOT_PASSWORD} -h db -e "show databases" && s=0 && break || s=$? && sleep 2; done
37if [ ! $s -eq 0 ]; then exit $s; fi
38
39# Init some stuff in db before leaving the floor to the application
40mysql -u root -p${MYSQL_ROOT_PASSWORD} -h db -e "create database my_app"
41mysql -u root -p${MYSQL_ROOT_PASSWORD} -h db -e "create table my_app.test (id int unsigned not null auto_increment primary key, myval varchar(255) not null)"
42mysql -u root -p${MYSQL_ROOT_PASSWORD} -h db -e "insert into my_app.test (myval) values ('toto'), ('pipo'), ('bingo')"
43The Dockerfile for the app container is trivial (adding a mysqli driver for php) and can be found in the example repo as well as the php script to test the init was succesful by calling http://localhost:9999 in your browser.
The interesting part is to observe what's going on when launching the service with docker-compose up -d.
The only limit to what can be done with such a feature is probably your imagination ;) Thanks for making me discovering this.
