Hi I am trying to run docker-compose build --no-cache but I keep getting errors.
yaml.parser.ParserError: while parsing a block mapping
in ".\docker-compose.yml", line 1, column 1
expected <block end>, but found '<block mapping start>'
in ".\docker-compose.yml", line 2, column 5
docker-compose.yml:
Please help me to to format this I looked online but I couldn't find any linter that could do this I keep getting errors.
Thanks.
This is my docker composer file:

I have noticed some spacing issues on your YAML file, one of them is that the version and services sections are not on the same level, you have to know that docker-compose files and YAML have a strict syntax and a spacing might ruin everything for you here is a fix to your compose file, make sure to learn and read more about docker-compose documentation.
Not sure what's the behavior of your environment but here is a correct YAML syntax for your example:
version: '3'

So I looked at this article: link
And I don't see the problem I made, so that's why I am asking.
The error I am getting is:
service "Appback" depends on undefined service -Sql-server: invalid compose project
And my docker-compose.yml file looks like this:
version: '3.8'
services:
Sql-server:
image: mysql:latest
environment:
MYSQL_DATABASE: *****
MYSQL_USER: ****
MYSQL_PASSWORD: *****
MYSQL_ROOT_PASSWORD: *****
ports:
- 3306:3306
expose:
- 3306
volumes:
- db:/var/lib/mysql
networks:
- appnetwork
Appback:
build:
context: ./AppBack
dockerfile: Dockerfile
ports:
- 8080:8080
depends_on:
-Sql-server:
condition: service_started
networks:
- appnetwork
appfront:
build:
context: ./appfront
dockerfile: Dockerfile
ports:
- 3000:3000
depends_on:
-Appback:
condition: service_started
networks:
- appnetwork
volumes:
db:
networks:
appnetwork:
driver: bridge
I don't see where the problem might be as I am also new to docker compose.
You should separate the -Sql-server: with a space - Sql-server: from the first hyphen character.
I saw the same error when you have -Appback: in the next few lines.
I am running Flask and MySQL using docker-compose.yaml.
Although I have specified a volume, the volume has not been created.
Why is this?

You need to remove the relative path as follows:
volumes:
- db-flask-data/:/var/lib/mysql
It is explained here: https://docs.docker.com/storage/volumes/#use-a-volume-with-docker-compose
Actually, you are creating a named volume under /var/lib/docker/volumes/db-flask-data when you are specifying the following command:

So my symfony code is in the /www/my-app window's folder. This includes the /www/my-app/vendor too.
My application is running extremely slow (50-70 seconds). If i'm correct it's because the vendor folder is huge (80MB) and docker creates an image of it every time. Other discussions mentioned that vendor folder sould be moved into a new volume, and here i'm stuck with it. How to move and mount that in this case, and how should the docker-compose.yml look like after it?

I have four services. Three of them work fine and no problem at all, but phpmyadmin doesn't work at all. The thing is all is work fine, database, webserver, but not phpMyAdmin. When I try to go to localhost:8080, it says site can't be reached. I don't know what's going on. What am I missing?
