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?

How can I get a full Backup from a Docker Container

I'm new to Docker and created myself a Container using a Compose File.
Now I came to a point where I wanted to use my development result in production.
Is there any way to backup the whole content so that I can use it in a production environment ?
The compose file that I used to spin up my Container:
version: '3.3'
services:
db:
image: mysql:5.7
volumes:
- db_data:/var/lib/mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: myRootPassword
MYSQL_DATABASE: wordpress_oxygen
MYSQL_USER: wordpress_oxygen
MYSQL_PASSWORD: myDBPassword
wordpress:
depends_on:
- db
image: wordpress:latest
ports:
- "8000:80"
restart: always
environment:
WORDPRESS_DB_HOST: db:3306
WORDPRESS_DB_USER: wordpress
WORDPRESS_DB_PASSWORD: wordpress
WORDPRESS_DB_NAME: wordpress
volumes:
db_data: {}
Docker compose is not for production. For production try docker swarm.
Also you should add volume for wordpress, see example
https://hub.docker.com/_/wordpress
How backup volumes please see https://docs.docker.com/storage/volumes/#backup-restore-or-migrate-data-volumes

Connect to networked mysql docker container with local client

I have just followed a tutorial on using Docker. I started with installing different containers and when I got to mysql, i installed it by running
docker container run -d -p 3306:3306 --name mysql --env MYSQL_ROOT_PASSWORD=123456 mysql
After the container has been created, I have been able to connect to MySQL with Heidi, by using 127.0.0.1, root and 123456 as password.
I eventually moved forward with another tutorial on installing WordPress with docker.
https://www.youtube.com/watch?v=pYhLEV-sRpY
The yaml for setting up the containers is bellow. Everything works just fine, but when it comes to connecting to the database using Heidi, I just do not get what to do - what connection data to use or what to change in the yaml to be able to connect from local machine.
version: '3'
services:
# Database
db:
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: wordpress
networks:
- wpsite
# phpmyadmin
phpmyadmin:
depends_on:
- db
image: phpmyadmin/phpmyadmin
restart: always
ports:
- '8080:80'
environment:
PMA_HOST: db
MYSQL_ROOT_PASSWORD: password
networks:
- wpsite
# Wordpress
wordpress:
depends_on:
- db
image: wordpress:latest
ports:
- '8000:80'
restart: always
volumes: ['./:/var/www/html']
environment:

You should expose 3306 port to local machine. Then, you can connect to MySQL by using host=127.0.0.1.
Update the yaml file like this:
version: '3'
services:
# Database
db:
image: mysql:5.7
volumes:
- db_data:/var/lib/mysql
restart: always
ports:
- "3306:3306"
environment:
MYSQL_ROOT_PASSWORD: password
MYSQL_DATABASE: wordpress
MYSQL_USER: wordpress
MYSQL_PASSWORD: wordpress
networks:
- wpsite

Unable to log into mysql with phpmyadmin

I'm new to the docker world and maybe I'm missing something.
I created the following docker-compose file
version: '3.3'
services:
db:
image: mysql:latest
restart: always
volumes:
- db_data:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: password
MYSQL_DATABASE: wordpress
MYSQL_USER: wordpress
MYSQL_PASSWORD: wordpress
networks:
- wpsite
phpmyadmin:
depends_on:
- db
image: phpmyadmin/phpmyadmin
ports:
- '8080:80'
environment:
PMA_HOST: db
MYSQL_ROOT_PASSWORD: password
networks:
- wpsite
wp:
depends_on:
- db
image: andreccosta/wordpress-xdebug
volumes:
- ./wp:/var/www/html
ports:
- 8000:80
restart: always
environment:
WORDPRESS_DB_HOST: db:3306
WORDPRESS_DB_USER: wordpress
WORDPRESS_DB_PASSWORD: wordpress
XDEBUG_CONFIG: remote_host=172.17.0.1
networks:
- wpsite
networks:
wpsite:
volumes:
db_data:
When i run it with docker-compose up everything goes well, but when I try to access localhost:8080 (path for phpmyadmin) and try to login i'm not able to connect to mysql.
If i try to enter the mysql container with
docker exec -t -i <conatiner_name> bash
and try to login to mysql i'm able to do it.
I used this same file on a different computer and everything works well.
I'm running docker on ubuntu.
UPDATE
I solved the issue by changing the version of the mysql image from latest to 5.7.27.

Docker volume must be a mapping, not a string

I have the following file at ./wordpress/docker-compose.yaml:
version: '3.3'
serivces:
db:
image: mysql:5.7
volumes:
- db_data:/var/lib/mysql
restart: always
evironment:
MYSQL_ROOT_PASSWORD: password
MYSQL_DATABASE: wordpress
MYSQL_USER: wordpress
MYSQL_PASSWORD: wordpress
wordpress:
depends_on:
- db
image: wordpress:latest
ports:
- "8000:80"
volumes:
- ./:/var/www/html
restart: always
environment:
WORDPRESS_DB_HOST: db:3306
WORDPRESS_DB_USER: wordpress
WORDPRESS_DB_PASSWORD: wordpress
volumes:
db_data
When I run cd ./wordpress && docker-compose up -d I get the following error:
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
volumes:
db_data:
driver: local
version: '3.3'
serivces:
db:
image: mysql:5.7
command: bash -c "mkdir -p /var/lib/mysql/"
volumes:
- db_data:/var/lib/mysql/
restart: always
evironment:
MYSQL_ROOT_PASSWORD: password
MYSQL_DATABASE: wordpress
MYSQL_USER: wordpress
MYSQL_PASSWORD: wordpress
wordpress:
depends_on:
- db
image: wordpress:latest
ports:
- "8000:80"
volumes:
- ./:/var/www/html
restart: always
environment:
WORDPRESS_DB_HOST: db:3306
WORDPRESS_DB_USER: wordpress
WORDPRESS_DB_PASSWORD: wordpress
volumes:
db_data: {}
save as docker-compose.yml
cd wordpress
docker-compose up
