Similar to other questions (see here and here) I'm getting the following error, both ways, with sudo or without:
/snap/docker/2343/lib/python3.6/site-packages/paramiko/transport.py:33: CryptographyDeprecationWarning: Python 3.6 is no longer supported by the Python core team. Therefore, support for it is deprecated in cryptography and will be removed in a future release.

I can see that a container that I imported in Docker-Desktop is running:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

According to answers to similar problems, I've tried the following already:
source ~/.bashrc (see here)
sudo groupadd docker plus sudo usermod -aG docker $USER (see here). groups is confirming that I am in the group docker.
sudo gpasswd -a $USER docker plus newgrp docker - doing the same as above, just to make sure everything has been tried (see here)
sudo chmod 666 /var/run/docker.sock (potentially unsafe, but it's only my development machine) (see here)
sudo service docker restart (sudo systemctl status docker.service in my case) (see here)
"Enable Docker Compose V1/V2 compatibility mode" is checked in Docker-Desktop (see here) though I guess this is unnecessary because of the initial line version: '3'.
I also wanted to set "WSL Integration" as recommended here but the option is not present in my version of Docker Desktop.
By the way, the same error appears when I say: $ docker-compose -f /home/bo/git/gokb/docker-compose-default.yml down.
How can I make the error disappear and compose?
I am a very-newbie to docker.
I am trying to get the web, db and redis services running via docker compose but my web container keeps going down. And on inspecting the logs, i see :- urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='localhost', port=8443): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7fc998b43070>: Failed to establish a new connection: [Errno 111] Connection refused'))
To Reproduce the issue :-
1. git clone https://github.com/PostHog/posthog && cd posthog and run docker-compose up -d
2. This is my docker compose file :-
services:
db:
container_name: posthog_db
environment:
POSTGRES_DB: posthog
POSTGRES_PASSWORD: posthog
POSTGRES_USER: posthog
image: postgres:alpine
volumes:

I have 3 containers who communicates and exchange data through each other by sending jobs via RabbitMQ.
Since yesterday, the last container to be executed in the workflow (encoder_aggregatore) exits as soon as it is built up:
$docker-compose up -d --build
[..]
$docker ps -a
0f521c4260a5 encoder_my-pre-encoder "python main.py" About an hour ago Up 20 minutes encoder_my-pre-encoder_1
72c3f5a2aa9c encoder_aggregatore "python /src/main.py" 18 hours ago Exited (1) 20 minutes ago encoder_aggregatore_1
dd9104e888ee encoder_classificatore "python /src/main.py" 20 hours ago Up 20 minutes 0.0.0.0:8080->5000/tcp encoder_classificatore_1
9
More info:
$docker inspect 72c3f5a2aa9c
The output is here.
I'm totally a newby in Docker. I do not know if it can help but I noticed that, if I edit the code of the "broken" container, the new code is compiled but executed on the "old" data job sent by container encoder_my-pre-encoder. I guess then that, for some reason, their communication broke.
Could you give me some hints on what it is going on?

The container compiles the "new" code I wrote to handle new data added by previous containers (encoder_my-pre-encoder, encoder_classificatore).
Since the aggregatore container does not receive new job, it fails to process the new code in the old data job.

I wrote a docker-compose file to run two services vernemq and nginx. When i run the command docker-compose up on my terminal, i keep on getting the error below.
If this might help, i am using a virtual machine with the ubuntu 18.04 image
I tried leaving the IP address away in the vernemq service but it didn't help.
Here is my docker compose file
version: "3.7"
services:
vernemq:
image: erlio/docker-vernemq:1.8.0
hostname: vernemq
container_name: vernemq
expose:
- "1883"
- "9001"
ports:
- "IPaddress:1883:1883"
- "IPaddress:9001:9001"
volumes:
- ./configvol:/etc/vernemq
- ./datavol:/var/lib/vernemq
- ./logvol:/var/log/vernemq
network_mode: "host"
nginx:
image: nginx:1.16.0
hostname: nginx
container_name: robotWebView
expose:
- "80"
ports:
- "80:80"
volumes:
- ./nginxvol:/usr/share/nginx/html
network_mode: "host"
and this is the error i get
# docker-compose up

[10433] Failed to execute script docker-compose
I'm triying to setup my containers with docker-compose in a docker container (docker:dind) to make the tests at gitlab ci.
From yesterday to today it has begin to fail on "docker-compose up" and i reduced the error to "ports" segment at service in docker-compose.yml. The simpliest configuration that fails is that:
version: '3':
services:
ubuntu:
image: ubuntu:latest
ports:
- 80:80
I've tried without ports and it works.
The specific error is this:
ERROR: for ubuntu expected string or buffer
Traceback (most recent call last):

TypeError: expected string or buffer
This is the steps to reproduce it:
(at your machine)
~ docker run --privileged -d docker:stable-dind
~ docker exec -ti *CONTAINER_ID* sh
(inside of the docker container)
~ apk add --no-cache py-pip vim
~ pip install docker-compose
(here edit a docker-compose.yml and paste the up yaml code)
~ docker-compose up
I don't know if is a problem with python, with docker, docker-compose....
Anybody can help me?
Thanks!
Error? the problem is most probably(not given) coming from your "docker-compose.yml" file, docker expected a string or bytes-like object but one or more of the values supplied doesn't conform to that format.
Solution - make sure the values supplied to your docker-compose.yml properties document are in the right format.
For example one time , i had the wrong spacing in the following property:
i.e it looked like;
ports:
- 8000: 8000
but should have been
ports:
- 8000:8000
Notice the spacing of the values supplied.
I encountered a similar error when working with a NestJS application on macOS.
When I run the command docker-compose up I get the error:

[21470] Failed to execute script docker-compose
Here's how I solved it
I checked the docker-compose.yml file and I realized that it did not have the container port specified. This was how the file looked:
version: "3"
services:
web:
image: my-app
build: .
container_name: my-app
ports:
- 8080:
env_file: .env
volumes:
- ".:/app"
All I had to do was to add the container port which was 3001:
version: "3"
services:
web:
image: my-app
build: .
container_name: my-app
ports:
- 8080:3001
env_file: .env
volumes:
- ".:/app"
