Following the tutorial at:
https://docs.docker.com/compose/wordpress/
Running docker-compose up I get:
Initializing database
[Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
[ERROR] --initialize specified but the data directory has files in it. Aborting.
[ERROR] Aborting
Have tried adding arguments as suggested here:
https://github.com/docker-library/mysql/issues/186
https://github.com/docker-library/mysql/issues/69
But this doesn't seems to work:
services:
db:
image: mysql:5.7
command: ["mysqld", "--ignore-db-dir=lost+found", "--explicit_defaults_for_timestamp"]
volumes:
- db_data:/var/lib/mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: somewordpress
MYSQL_DATABASE: wordpress
MYSQL_USER: wordpress
MYSQL_PASSWORD: wordpress
Is there another solution?
I solved it using:
docker volume prune
Remove all unused local volumes. Unused local volumes are those which
are not referenced by any containers
https://docs.docker.com/engine/reference/commandline/volume_prune/

I'm new to docker and I'm following this guide to setup my mac (the guide is for linux but is not the point) for a PHP dev env with docker-compose.
The guide is quite good and everything seems to work correctly, there is just a part that doesn't seem to work.
If you go to Step 9 — Creating a User for MySQL, I'm running docker-compose up and I have these errors so I can't access the db container.
mysqld: Error on realpath() on '/var/lib/mysql-files' (Error 2 - No such file or directory)

If I remove the - ./mysql/my.cnf:/etc/mysql/my.cnf from the volumes everything seem to work but then for some reason my laravel db is not created.
these command is not supposed to already create a DB?
environment:
MYSQL_DATABASE: laravel
MYSQL_ROOT_PASSWORD: root
another question is where the data is stored?
db:
...
volumes:
- dbdata:/var/lib/mysql
...
#Volumes
volumes:
dbdata:
driver: local
how it works that driver local and what is the location of it?
I just found out that the tutorial uses a wrong path, the correct path is:
- ./mysql/my.cnf:/etc/my.cnf
and not:
- ./mysql/my.cnf:/etc/mysql/my.cnf
docker-compose.yml

If I execute the "docker-compose up -d" command and that I open the logs of the wordpress container I have this error:
...

I added command: '--default-authentication plugin=mysql_native_password' in the db section and i changed the mysql version to 5.7 but it did not help me solve the problem.
I also visited these discussions :

Thank you in advance for your proposals.
It seems that WordPress/PHP doesn't support MySQL v8 yet. Even wordpress docker image readme suggests to use MySQL v5.7. After changing mysql version to v5.7, you might notice that MySQL container crashes with an error similar to below:
...
db_1 | 2019-01-28T18:45:24.611045Z 0 [ERROR] [FATAL] InnoDB: Table flags are 0 in the data dictionary but the flags in file ./ibdata1 are 0x4800!

db_1 | InnoDB: We intentionally generate a memory trap.
...
To fix this, easiest way is to delete the MySQL docker volume using docker-compose down -v. After that, docker-compose up -d should work.
If that still doesn't work, use the docker-compose example from https://hub.docker.com/_/wordpress/. Adding it here in case it gets pulled down in future.

There are some files in /var/lib/mysql directory. Remove everything from this directory.
Or highly recommended, use volumes in docker-compose.yml.
volumes:
- /my/own/datadir:/var/lib/mysql
Update:
I tested with the following compose file, it worked fine without any errors.
version: '3.7'
services:
db:
image: mysql:5.7
restart: always
volumes:
- ./data:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: pass
MYSQL_DATABASE: star
MYSQL_USER: user
MYSQL_PASSWORD: pass
For those who ran the container using the docker run command and added the --detach|-d flag; Remove and rerun the container without the -d flag.
This should provide the error message to why it fails.
I got the same behaviour defining restaart=always, If I remove it everything went fine, and later I run command
docker update --restart=always {{ID OF CONTAINER}}
Which makes it restart always. Hope this helps you.
Update Volume in docker-compose.yml
volumes:
- /my/own/datadir:/var/lib/mysql
Update: this compose file, it worked fine .

I'm new on Docker and trying now to create my first docker-compose file.
The apache works so far but i'm struggeling a bit with mysql.
Here is my docker-compose.yaml
version: '3'
services:
web:
build: .
ports:
- "8083:80"
volumes:
- ./public_html/:/usr/local/apache2/htdocs/

networks:

adminer:

ports:

volumes:
db-data:
networks:
appnet:
The error is:
[ERROR] [MY-010457] [Server] --initialize specified but the data directory has files in it. Aborting.
I alread tried to remove the volume totally or added a /data at the end. But it gives me all the time the same error. Also Google didn't give me any good hints.
Does someone has an idea?
I figured out now. I'm running Docker on a Windows Machine, so i had to reset the credentials ond Docker App and type in again. Now it works. Hope that will help others as well. It seems on Docker for Windows, when something not work as expected it make sense to reset the credentials.
I am trying to use Docker to create a set of containers (wordpress and MySQL) that will help my local development with Wordpress. As we are running a live database, I want to mount a dump.sql file into the Docker mysql container. Below is my .yml file.
version: '2'
services:
db:
image: mysql:latest
volumes:
- ./data:/docker-entrypoint-initdb.d #./data holders my dump.sql file
environment:
MYSQL_ROOT_PASSWORD: wordpress
MYSQL_DATABASE: wordpress
MYSQL_USER: wordpress
MYSQL_PASSWORD: wordpress
wordpress:
depends_on:
- db
image: wordpress:latest
ports:
- "8000:80"
restart: always
environment:
WORDPRESS_DB_HOST: db:3306
WORDPRESS_DB_PASSWORD: wordpress
volumes:
- ./wp-content/themes/portalV3:/var/www/html/wp-content/themes/portalV3
- ./wp-content/plugins:/var/www/html/wp-content/plugins
- ./wp-content/uploads:/var/www/html/wp-content/uploads
Everything works, but after ~10 seconds the docker container for mysql crashes. Going through the logs, I get the following error:
/usr/local/bin/docker-entrypoint.sh: running /docker-entrypoint-initdb.d/dump.sql
mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR: Can't initialize batch_readline - may be the input source is a directory or a block device.
On closer inspection (attaching to the rebooted mysql container) I see that indeed my dump.sql file wasn't transferred to the container, but a folder with the same name was created in /docker-entrypoint-initdb.d.
Can anyone help me understand how I get docker-compose to copy my dump.sql file and import into the database?
Cheers,
Pieter
The problem you got with docker-entrypoint-initdb.d is that because your source 'data' is a directory and not a file, The destination file (docker-entrypoint-initdb.d) must be a directory too. And vice versa.
So either do
volumes:
- ./data:/docker-entrypoint-initdb.d/
or
volumes:
- ./data/mydump.sql:/docker-entrypoint-initdb.d/mydump.sql
Yes, that is how you should mount the .sql or .sh files i.e by adding a volume by mapping the SQL or .sh files to the docker container's docker-entrypoint-initdb.d folder. But, it's raising an error for some strange reason maybe because the MySQL docker version is old.
You could solve this by creating a custom image i.e,
Dockerfile
FROM mysql:5.7
COPY init.sql /docker-entrypoint-initdb.d/
It creates an image and also helps in running a init script while starting the container.
To use this in a compose file, put your SQL files and Dockerfile in a folder.
database
|---init.sql
|---Dockerfile
docker-compose.yml
version: '3'
services:
mysqldb:
image: mysqldb
build: ./database
container_name: mysql
ports:
- "3306:3306"
environment:
- MYSQL_ROOT_PASSWORD=root
- MYSQL_USER=test
- MYSQL_PASSWORD=root
- MYSQL_DATABASE=test
By this, you could configure the environment variables easily.
