This is how my docker-compose file looks
version: '3.3'
services:
frontend:
ports:
- 8000:8000
build: ./frontend
api:
build: ./api
ports:
- 8080:8080
reverse-proxy:
image: nginx:1.21
depends_on:
- api
- frontend
volumes:
- ./nginx-conf:/etc/nginx/conf.d
ports:
- 80:80
- 443:443
i if I run docker-compose build on the above file I am getting the following error
ERROR: compose.cli.main.main: yaml.scanner.ScannerError: while scanning for the next token
found character '\t' that cannot start any token
in "./docker-compose.yaml", line 3, column 1
I have tried changing the version as well as correcting the spaces/tabs but nothing works
The indentation of services and version should be at the same level, so your docker-compose file should look like this:
version: '3.3'
services:
frontend:
ports:
- 8000:8000
build: ./frontend
api:
build: ./api
ports:
- 8080:8080
reverse-proxy:
image: nginx:1.21
depends_on:
- api
- frontend
volumes:
- ./nginx-conf:/etc/nginx/conf.d
ports:
- 80:80
- 443:443

I am trying to get a couple of containers up and running, however I am running into some issues. I run this command:
docker-compose up -d --build itvdflab
and get this error
The Compose file './docker-compose.yaml' is invalid because:
Unsupported config option for services: 'itvdelab'
Unsupported config option for networks: 'itvdelabnw'
Here is the yaml file.
services:
itvdelab:
image: itversity/itvdelab
hostname: itvdelab
ports:
- "8888:8888"
volumes:
- "./itversity-material:/home/itversity/itversity-material"
- "./data:/data"
environment:
SHELL: /bin/bash
networks:
- itvdelabnw
depends_on:
- "cluster_util_db"
cluster_util_db:
image: postgres:13
ports:

volumes:
- ./cluster_util_db_scripts:/docker-entrypoint-initdb.d
networks:

environment:

itvdflab:

ports:

networks:

What changes do I need to make to get this working?
Your docker-compose.yml file is missing a version: line. Until very recently, this caused Docker Compose to interpret this as the original "version 1" Compose format, which doesn't have a top-level services: key and doesn't support Docker networks. The much newer Compose Specification claims that a version: key is optional, but in practice if you can't be guaranteed to use a very new version of Compose (built as a plugin to the docker binary) it's required. The most recent Compose file versions supported by the standalone Python docker-compose tool are 3.8 and 2.4 (you need the 2.x version for some resource-related constraints in non-Swarm installations).
# Add at the very beginning
version: '3.8'
Here is the revised copy:
version: '3.4'
services:
itvdelab:
image: itversity/itvdelab
hostname: itvdelab
ports:
- "8888:8888"
volumes:
- "./itversity-material:/home/itversity/itversity-material"
- "./data:/data"
environment:
SHELL: /bin/bash
networks:
- itvdelabnw
depends_on:
- "cluster_util_db"
cluster_util_db:
image: postgres:13
ports:
- "6432:5432"
volumes:
- ./cluster_util_db_scripts:/docker-entrypoint-initdb.d
networks:
- itvdelabnw
environment:
POSTGRES_PASSWORD: itversity
itvdflab:
build:
context: .
dockerfile: images/pythonsql/Dockerfile
hostname: itvdflab
ports:
- "8888:8888"
volumes:
- "./itversity-material:/home/itversity/itversity-material"
- "./data:/data"
environment:
SHELL: /bin/bash
networks:
- itvdelabnw
depends_on:
- "pg.itversity.com"
pg.itversity.com:
image: postgres:13
ports:
- "5432:5432"
networks:
- itvdelabnw
environment:
POSTGRES_PASSWORD: itversity
networks:
itvdelabnw:
name: itvdelabnw
and now I get the following error
ERROR: The Compose file './docker-compose.yaml' is invalid because:
services.pg.itversity.com.networks.itvdelabnw contains unsupported option: 'name'
for me work try different version. In my case work
version: '2.2'
I have set up the docker registry at DigitalOcean to deploy my django application.
I have installed the doctl and setup the API credentials.
If I run the command as:
doctl auth list
i can see my auth as the current one, which has the Read and Write permission.
But now, when I try to run the command as:
docker-compose -f docker-compose.staging.yml push
I get the error as:

Make sure your port 80 isn't already in use.
Also, here's a thread with several possible solutions.
My docker-compose.yml looks like the below. When i run docker-compose up I get the below error.

My docker version is
Docker version 18.06.1-ce, build e68fc7a
My docker compose version is
docker-compose version 1.23.1, build b02f1306
Running CoreOS version 1911.3.0
I ended up resolving this issue by modifying the nginx and letsencrypt portions of my docker-compose.yml file to be as follows.
nginx:
image: jwilder/nginx-proxy
container_name: nginx
volumes:
- /var/run/docker.sock:/tmp/docker.sock:ro
- /apps/docker-articles/nginx/vhost.d:/etc/nginx/vhost.d

restart: always
ports:
- "80:80"
- "443:443"
labels:
- "NGINX_PROXY_CONTAINER=true"
networks:

letsencrypt:
image: jrcs/letsencrypt-nginx-proxy-companion:v1.5
container_name: letsencrypt
environment:
- NGINX_PROXY_CONTAINER=true
volumes:
- /var/run/docker.sock:/var/run/docker.sock:ro

- /apps/docker/articles/nginx/certs:/etc/nginx/certs:rw
- /apps/docker-articles/nginx/html:/usr/share/nginx/html
It seems "volumes_from" is deprecated in docker-compose v3. As well as I had forgotted quotes around my label and needed to set my environment within letsencrypt.
in CentOS env your .yml file directory must be /usr/local/bin
I have a yml file with a configuration to run two containers. Here's the file:
web:
build: ./web
ports:
- "8000:8000"
restart: always
volumes:
- website:/www/
nginx:
build: ./nginx
ports:
- "80:80"
restart: always
links:
- web
volumes:
- website:/www/
volumes:
website:
When I run this I always get the following error:
The Compose file '.\docker-compose.yml' is invalid because:
Unsupported config option for volumes: 'website'
I have googled this and I think this is good as it is now. What is wrong with it?
i think you should add version and services in docker-compose file.
version: '3'
services:
web:
build: ./web
ports:
- "8000:8000"
restart: always
volumes:
- website:/www/
nginx:
build: ./nginx
ports:
- "80:80"
restart: always
links:
- web
volumes:
- website:/www/
volumes:
website:
