Managing DBs in DDEV

### 1. **Configure Separate Databases for Each Project**
Each DDEV project can have its own database. When you create a new project in DDEV, it automatically sets up a MySQL or MariaDB container (depending on your setup). For each project, DDEV will configure its database with a separate schema.

– In your `ddev/config.yaml`, you'll find the database configuration, which typically looks like this:

# Example config.yaml for a Laravel project
name: my-project
type: php
php_version: "8.3"
webserver_type: apache-fpm
router_http_port: "8080"
router_https_port: "8443"
database:
  user: dbuser
  password: dbpassword
  name: myproject_db
  host: db

Make sure each project has its own unique database name.

### 2. **Exporting/Importing Databases**
To move data between multiple projects, you can use DDEV's `ddev export-db` and `ddev import-db` commands.

– **Exporting a Database:**
You can export the database from one project using:

ddev export-db --file=my_project_db.sql

This will export the database of your current project to a `.sql` file.

– **Importing a Database:**
You can import the exported database into another project by running:

ddev import-db --file=my_project_db.sql

Ensure that you’re in the correct DDEV project directory when importing.

### 3. **Sharing Databases Between Projects**
If you want to share a database between multiple DDEV projects (for example, common data between them), you can point to an external database. DDEV allows you to configure a database connection to an external service in the `config.yaml`.

You’ll need to adjust the `database` section to use the external database host and credentials.

database:
  user: external_dbuser
  password: external_dbpassword
  name: shared_db
  host: external_host

### 4. **Multi-Database Setup in Laravel**
If you're using Laravel and need to manage multiple databases, you can configure them in the `config/database.php` file. Here’s an example for two databases:

'mysql' => [
    'driver' => 'mysql',
    'host' => env('DB_HOST', 'localhost'),
    'port' => env('DB_PORT', '3306'),
    'database' => env('DB_DATABASE', 'database1'),
    'username' => env('DB_USERNAME', 'root'),
    'password' => env('DB_PASSWORD', ''),
    'unix_socket' => env('DB_SOCKET', ''),
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
],

'other_connection' => [
    'driver' => 'mysql',
    'host' => env('DB_HOST', 'localhost'),
    'port' => env('DB_PORT', '3306'),
    'database' => env('DB_DATABASE', 'database2'),
    'username' => env('DB_USERNAME', 'root'),
    'password' => env('DB_PASSWORD', ''),
    'unix_socket' => env('DB_SOCKET', ''),
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
],

This way, Laravel can interact with multiple databases seamlessly.

By combining these strategies, you can effectively manage multiple databases across different DDEV projects. Would you like to dive deeper into any specific part of this process?

This issue typically arises when:

1. **The database service name is incorrect.**
2. **The database container is not running or isn't accessible.**

### Steps to troubleshoot:

1. **Check the Database Host in `.env`:**

Ensure that the database host in your `.env` file is set to the correct service name used by DDEV. For example:

DB_CONNECTION=mysql
   DB_HOST=db
   DB_PORT=3306
   DB_DATABASE=shareyourthoughts
   DB_USERNAME=root
   DB_PASSWORD=root

The `DB_HOST=db` refers to the service name `db` that is typically set up in DDEV's `docker-compose` configuration.

2. **Verify DDEV Configuration:**

Run `ddev describe` in your project folder. It will give you information about the database service and its container status. The database service name should match what is in the `.env` file (`db` in this case).

3. **Check the Database Container:**

Ensure the MariaDB (or MySQL) container is running. Use the following command to check the status:

ddev list

If the container isn’t running, start it using:

ddev start

4. **Network Issues:**

The `getaddrinfo` error can also occur if there's a network issue between the Laravel app and the MariaDB container. Try restarting DDEV:

ddev restart

5. **Database Container Name Change:**

If you've modified the database service name in DDEV (e.g., from `db` to something else), make sure the `.env` file reflects that change.

6. **Verify Docker Network:**

If you're running multiple DDEV projects, ensure they are all on the same Docker network and can communicate with each other. You can check the network configuration of your DDEV project using:

docker network inspect ddev_default

This will list the containers in the default network. Your app container should be able to connect to the `db` container.

### Quick Fix:
If everything is correct and the issue persists, try setting the database host in the `.env` file to the container's IP address instead of the service name (though this is usually not recommended because it might change):

DB_HOST=127.0.0.1

This can help identify if the issue is due to DNS resolution inside the container.

### Here’s how you can resolve it:

#### 1. **Check the `.env` Database Configuration**
Make sure your `.env` file has the correct configuration for the database host, which should be the service name for the MariaDB container.

DB_CONNECTION=mysql
DB_HOST=db
DB_PORT=3306
DB_DATABASE=shareyourthoughts
DB_USERNAME=root
DB_PASSWORD=root

In DDEV, the database container service is usually called `db`. If you've changed the name of the database service, update this to reflect the correct service name.

#### 2. **Verify DDEV Configuration**
Use the `ddev describe` command to check if the `db` service is correctly named and running.

ddev describe

Look for the `db` service and make sure it matches the `DB_HOST=db` setting in the `.env` file.

#### 3. **Check DDEV Containers**
If the database container is not running, start it using:

ddev start

Then, check the status again with:

ddev list

If you don’t see your project listed or the database container is not running, try restarting the entire project:

ddev restart

#### 4. **Confirm Database Container is Reachable**
You can inspect the containers to ensure the `db` service is properly linked to your web service. Run:

docker ps

Look for the container that is running the `db` service (e.g., `db_1`) and check if it’s up and running. If necessary, restart it:

ddev restart

#### 5. **Test Database Connection with Docker CLI**
If you're unsure whether the `db` container is reachable, you can try to connect to it manually from within the web container:

ddev ssh
mysql -h db -u root -p

This will allow you to confirm if the `db` hostname is resolvable inside the DDEV environment.

#### 6. **Check for DNS Resolution Issues**
Sometimes, DNS resolution within Docker containers can have issues. Try setting the database host to `127.0.0.1` (or `localhost`) in the `.env` file:

DB_HOST=127.0.0.1

This will use the local machine’s IP for the database connection. This is more of a workaround, but it can help troubleshoot if DNS issues are causing the problem.

#### 7. **Inspect the Docker Network**
If you're working with multiple DDEV projects, ensure they are on the same Docker network,

Here's a more focused troubleshooting guide to resolve the issue:

### 1. **Verify DDEV's Database Service Name:**
DDEV assigns a service name for the database container (typically `db`). Ensure that the correct database host is specified in the `.env` file for your project.

Open the `.env` file and confirm that the `DB_HOST` is set to `db` (or the name of the database service container, if it’s different).

DB_CONNECTION=mysql
   DB_HOST=db
   DB_PORT=3306
   DB_DATABASE=shareyourthoughts
   DB_USERNAME=root
   DB_PASSWORD=root

If the name of the database service has changed in DDEV (check `docker-compose` or `ddev describe`), update the `DB_HOST` to match the new service name.

### 2. **Check if the DDEV Containers Are Running:**
Ensure that the DDEV containers, including the database container, are running properly. You can check the status of your DDEV project by running:

ddev describe

This will show the status of the database container. If the database container is down, start your DDEV environment:

ddev start

### 3. **Test Database Connection Inside the Container:**
You can test the database connection directly inside the web container to verify that it can reach the database service. Run:

ddev ssh

Once inside the container, try pinging the `db` service:

ping db

If it doesn't resolve, there might be an issue with the Docker network or service name.

### 4. **Check the Database Container Logs:**
To see if there are any errors in the database container, check its logs:

ddev logs db

This may reveal issues with the MariaDB or MySQL service inside the container.

### 5. **Check Docker Network Configuration:**
If you're running multiple DDEV projects, make sure they are connected to the same Docker network. You can inspect the Docker network by running:

docker network inspect ddev_default

This will list all containers in the `ddev_default` network. Ensure that your web container can communicate with the `db` container.

### 6. **Rebuild DDEV Project:**
If the problem persists, try rebuilding the project to ensure everything is set up correctly:

ddev restart

If needed, you can also rebuild the containers:

ddev stop
   ddev start

### 7. **Check for Database Host Configuration in `config/database.php`:**
In Laravel's `config/database.php`, ensure the database configuration matches the settings in your `.env` file:

'connections' => [
       'mysql' => [
           'driver' => 'mysql',
           'host' => env('DB_HOST', 'db'),  // Ensure this matches the DB_HOST in .env
           'port' => env('DB_PORT', '3306'),
           'database' => env('DB_DATABASE', 'shareyourthoughts'),
           'username' => env('DB_USERNAME', 'root'),
           'password' => env('DB_PASSWORD', ''),
           'unix_socket' => env('DB_SOCKET', ''),
           'charset' => 'utf8mb4',
           'collation' => 'utf8mb4_unicode_ci',
       ],
   ],

### 8. **Restart DDEV and Clear Cache:**
Sometimes, Laravel caches the configuration, so clearing the cache after ensuring everything is correct might help:

ddev ssh
   php artisan config:clear
   php artisan cache:clear

# upload_dirs: "custom/upload/dir"
#
# upload_dirs:
# – custom/upload/dir
# – ../private
#
# would set the destination paths for ddev import-files to /custom/upload/dir

# host_webserver_port: "59001"
# The host port binding for the ddev-webserver can be explicitly specified. It is

# mailpit_https_port: "8026"
# The Mailpit ports can be changed from the default 8025 and 8026

# host_mailpit_port: "8025"
# The mailpit port is not normally bound on the host at all, instead being routed

# – SOMEOTHERENV=someothervalue

# no_project_mount: false
# (Experimental) If true, DDEV will not mount the project into the web container;
# the user is responsible for mounting it manually or via a script.
# This is to enable experimentation with alternate file mounting strategies.
# For advanced users only!

# bind_all_interfaces: false
# If true, host ports will be bound on all network interfaces,
# not the localhost interface only. This means that ports
# will be available on the local network if the host firewall
# allows it.

# default_container_timeout: 120
# The default time that DDEV waits for all containers to become ready can be increased from
# the default 120. This helps in importing huge databases, for example.

#web_extra_exposed_ports:
#- name: nodejs
# container_port: 3000
# http_port: 2999
# https_port: 3000
#- name: something
# container_port: 4000
# https_port: 4000
# http_port: 3999
# Allows a set of extra ports to be exposed via ddev-router
# Fill in all three fields even if you don’t intend to use the https_port!
# If you don’t add https_port, then it defaults to 0 and ddev-router will fail to start.
#
# The port behavior on the ddev-webserver must be arranged separately, for example
# using web_extra_daemons.
# For example, with a web app on port 3000 inside the container, this config would
# expose that web app on https://.ddev.site:9999 and http://.ddev.site:9998
# web_extra_exposed_ports:
# – name: myapp
# container_port: 3000
# http_port: 9998

# command: "/var/www/html/node_modules/.bin/http-server /var/www/html/sub -p 3000"
# directory: /var/www/html

# override_config: false
# By default, config.*.yaml files are *merged* into the configuration
# But this means that some things can't be overridden
# For example, if you have 'use_dns_when_possible: true'' you can't override it with a merge
# and you can't erase existing hooks or all environment variables.
# However, with "override_config: true" in a particular config.*.yaml file,
# 'use_dns_when_possible: false' can override the existing values, and
# hooks:
# post-start: []
# or
# web_environment: []
# or
# additional_hostnames: []
# can have their intended affect. 'override_config' affects only behavior of the
# config.*.yaml file it exists in.

# Many DDEV commands can be extended to run tasks before or after the

# Performance optimization options:
# performance_mode: "mutagen"  # Adjust depending on your system for best performance.

# Set project-level domain TLD for local development:
# project_tld: ddev.site

# Enable extra ports if you need them exposed for specific services:
# web_extra_exposed_ports:
#   - name: nodejs
#     container_port: 3000
#     http_port: 2999
#     https_port: 3000

# Example of extending DDEV commands via hooks:
# hooks:
#   post-start: ["echo 'Project started!'"]
#   post-import-db: ["echo 'Database import completed!'"]

### Notes:
– **Web Server**: You're using `nginx-fpm`, which is appropriate for Laravel.
– **Database**: MariaDB 10.11 is specified.
– **Composer**: Version 2 is already set, which is good for modern Laravel setups.
– **Optional settings**: You can modify this further with features like exposed ports, performance optimizations, and custom hooks if needed.
– **Web Environment**: You may want to add environment variables to configure your Laravel application, such as `APP_KEY`, `DB_CONNECTION`, etc.

Let me know if you need any specific adjustments!

In this configuration:
– `type: mariadb` specifies the database type.
– `version: "10.11"` specifies the version of MariaDB.
– `host: db` points to the database container in the DDEV environment (it may also be named differently depending on your setup).
– `port: 3306` is the default MariaDB port.
– `username: dbuser`, `password: dbpassword`, and `dbname: dbname` are placeholders for your actual database credentials. Make sure to replace them with the correct values as needed.

Let me know if you'd like to modify any of these details or add something else!

Here are a few things to check and try:

1. **Check the Database Host Name**:
Ensure that the host name `db` matches the name of the database service in your Docker setup. For example, if you're using Docker Compose, check the service name for the database in your `docker-compose.yml`. It should look something like this:

services:
     db:
       image: mariadb:10.11
       container_name: db
       environment:
         MYSQL_ROOT_PASSWORD: rootpassword
         MYSQL_DATABASE: dbname
         MYSQL_USER: dbuser
         MYSQL_PASSWORD: dbpassword

Ensure that `db` matches the host name in your `.env` file for the database connection.

2. **Check the `.env` File**:
Ensure that the `DB_HOST` in your `.env` file points to the correct host name. It should look something like:

DB_CONNECTION=mysql
   DB_HOST=db
   DB_PORT=3306
   DB_DATABASE=dbname
   DB_USERNAME=dbuser
   DB_PASSWORD=dbpassword

3. **Database Service Dependency**:
Ensure that the Laravel app waits for the database container to be fully ready before starting. You can do this by adding a `depends_on` directive in your `docker-compose.yml`:

services:
     app:
       image: your-laravel-image
       depends_on:
         - db

4. **Network Configuration**:
Ensure both containers (`app` and `db`) are on the same network. Docker Compose usually handles this automatically, but check that the containers are part of the same network if you're not using Docker Compose.

5. **Clear Config Cache**:
Sometimes, cached configurations can cause issues. Run the following commands to clear the cache and configuration:

php artisan config:clear
   php artisan cache:clear

6. **Test the Connection**:
You can test the connection to the database from the Laravel container by running a simple MySQL client command inside the container (if the client is installed):

docker exec -it your-app-container-name bash
   mysql -h db -u dbuser -p

Enter the password and see if you can connect to the database.

1. **Check DDEV Database Service:**
– Ensure that the database service (e.g., MariaDB) is running correctly. You can check by running:

ddev list

This will show the status of your DDEV environment and whether the database container is up.

2. **Verify Database Hostname:**
– DDEV typically uses the service name `db` for the database, so in your `.env` file, ensure that the `DB_HOST` is set to `db`, like so:

DB_HOST=db

3. **Check Database Credentials:**
– Ensure that the database name, username, and password in your `.env` file are correct:

DB_CONNECTION=mysql
     DB_HOST=db
     DB_PORT=3306
     DB_DATABASE=your_database
     DB_USERNAME=root
     DB_PASSWORD=root

4. **Check DDEV Logs:**
– Run `ddev logs` to see if there are any issues with the database container that might be affecting the connection.

5. **Rebuild DDEV Containers:**
– If everything appears in order and it's still failing, try rebuilding your DDEV containers:

ddev restart

6. **Accessing the Database:**
– If the error persists, try accessing the database directly using DDEV’s database CLI:

ddev ssh
     mysql -u root -p
