Error as below-
ERROR: yaml.scanner.ScannerError: while scanning a simple key
in "./docker-compose.yml", line 21, column 3
could not find expected ':'

Can anyone please help me to resolve this issue? I am trying to resolve since past 1 hour but getting into errors one by one
The problem is probably in the definition of the wordpress1 service.
You need to add a space after the dash:
wordpress1:
depends_on:
- db
So instead of -db you need to have - db.
Edit:
The complete docker-compose.yml should probably look like this:
version: '3.0'
services:
db:
image: mysql
volumes:
- db_data:/var/lib/mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: 1234
MYSQL_USER: wordpress
MYSQL_PASSWORD: 12345
wordpress1:
depends_on:
- db
image: wordpress:latest
restart: always
ports:
- "8080:80"
environment:
WORDPRESS_DB_USER: wordpress
WORDPRESS_DB_PASSWORD: wordpress
WORDPRESS_DB_HOST: db:3306

I searched for stackoverflow but found nothing.
Thank you for your help
If you are not defining your db volume data is not persisting on restart. Just btw.
Furthermore it's a good practice to pin your image to a version like mysql:5.7.
Did you try that one here?

I am creating containers for all my projects, mostly in Wordpress, and I was wondering if for example I could upload several projects at the same time, because in this configuration that I use the docker, I have to disable one, in order to activate another. Example project1.local and project2.local, how could you do it that way?
docker-compose.yml

wordpress:
build: .

Dockerfile
FROM wordpress
RUN chown -R www-data:www-data /var/www/html
There are some things that you can do:
1- Since you've declare:
ports:
- 80:80
You can't get to many wordpress at the same time with different docker-compose. So, you can delete the binding from your instance like this:
ports:
- 80
Doing it, you can make several docker-compose with different ports without worrying about the ports.
But there is another problem... Your database it's already up. So, in this case, if you want to use several docker-compose for each project you'll need another docker-compose for your database. So... the docker-compose solution is get another docker-compose for your database and in every docker-compose file add an external network:
With it, you can use the dns name as its always.
The other way is using the same template like this:
version: '3.3'
networks:
default:
external:
name: wordpresses
services:
wordpress_1:
build: .
container_name: ${APP_NAME}-wordpress
restart: always

I know wordpress has some issues if you don't put the domain. In any case, you can use a NGINX in front of all wordpress as a reverse proxy like this Example.
Feel free to ask!
I have been trying to understand this process of having an docker-compse.yml file that I can re-use for many production with diffrent hosts, sql password and user and so on.
I've been trying out on this file fx.
services:
db_node_domain:
image: mysql:5.7
volumes:
- db_data:/var/lib/mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: PASSWORD
MYSQL_DATABASE: wordpress
MYSQL_USER: wordpress
MYSQL_PASSWORD: PASSWORD
container_name: wordpress_db
wordpress:
depends_on:
- db_node_domain
image: wordpress:latest
expose:
- 80:80
restart: always
environment:
VIRTUAL_HOST: sub.domain.example
WORDPRESS_DB_HOST: db_node_domain:3306
WORDPRESS_DB_USER: wordpress
WORDPRESS_DB_PASSWORD: $TEST
container_name: wordpress
volumes:
db_data:
networks:
default:
external:
name: nginx-proxy
And then I've tried to use varibales in gitlab to change the WORDPRESS_DB_PASSWORD in many ways. This is just one example of trying.
I also tried to use sed -i in .gitlab-ci.yml to change password but I wanted to know if someone could help me out on how to do this.
Thx
You just need to replace hardcoded creds with environment variables.
Then each stages will have creds/settings.
In Gitlab go your project, then Settings > "CI / CD" > Variables.
Then populate each ENV variable needed, hey will be present on each run

I have two directories each running an identical docker build except for the allocated ports. I cannot connect to one of the containers in my localhost.
After running the docker ps command I see that 80/tcp being prepended to my second recipe-blog container. Below is my yml file, its nothing crazy, just setting up a database running php my admin and have it connect to a WordPress install. I also attached an image of the docker ps command.

Once again - finalsandbox_ I can connect to fine, I cannot connect to recipe-blog_. The only difference between the two yml files is that for the recipe-blog_ I changed the ports to be 9090:90 instead of 8080:80 and 9000:90 instead of 8000:80.
Thanks in advance.

Change all the ports assigned by 90 to 80.

with your we-browser favorite, connect to http://127.0.0.1:9000 and http://127.0.0.1:9090

ERROR: In file './docker-compose.yaml', volume must be a mapping, not a string.
Can anyone tell me what I'm doing wrong?
There are certain typo errors first of, like serivces, evironment. They should spell services and environment. Also for the "... not string" error, just append ":" after your volume name like below
volumes:
db_data:
I had the same problem just now and the key was the indentation of the volume name i.e. db_data.
I fixed it by putting the volume name on the same level of indentation as the depends_on under the wordpress service in the example above. (hit TAB)
volumes:
mydata:
vs
volumes:
mydata:
that's will fix it and it works for me
