Migration

1. For both, local and remote instances of WordPress, install the plugin: https://wordpress.org/plugins/all-in-one-wp-migration/

2. For the local instance, open WordPress admin dashboard and find All-In-One-WP-Migration/Export tab

3. Fill the field: "Find text Replace with another-text in the database, e.g. "Find localhost Replace with yoursite.com in the database or http:// to https://" (replacing http://localhost to https://yoursite.com should be enough)

4. Choose "Export to file" and wait for finishing - the backup file will be saved on your local machine

5. For the remote website instance, open WordPress admin dashboard and find All-In-One-WP-Migration/Import tab

6. Click "Import from file", find save the backup file, confirm, and wait for completion

Troubleshooting

Bind for 0.0.0.0:8081 failed: port is already allocated

Run the following command to identify the container which uses the port and remove it:

docker container ls
docker rm -f <container-name>

or remove all containers at once (repeat running until all are killed):

docker rm $(docker ps -a -q) -f
