then

1. Check what process occupies the port:

   sudo lsof -nPi:80 | grep LISTEN

2. Stop the process or make it use a different port.

3. Run docker/sdk up again.

when

you get an error similar to this after running docker/sdk up:

docker: Error response from daemon: Conflict. The container name "/data-sync" is already in use by container "47dd708a7a7f9550390432289bd85fe0e4491b080748fcbba7ddb3331de2c7e7". You have to remove (or rename) that container to be able to reuse that name.

then

1. Run docker-sync clean
2. Run docker/sdk up again.

you get an error similar to this:

Unable to find image "eugenmayer/unison:hostsync_@.2' Locally
docker: Error response from daemon: manifest for eugenmayer/unison:hostsync_@.2 not found: manifest unknown: manifest unknown.

update docker-sync:

gem install docker-sync

1. Make sure your IDE is listening to the 9000 port.
2. Get into any application container:

   $ docker exec -i spryker_zed_1 bash

3. Check that xdebug extension is active:

   $ docker/sdk cli php -m

4. Check if the host is accessible from the container:

   $ nc -zv ${SPRYKER_XDEBUG_HOST_IP} 9000

when

PHP xdebug extension is not active

then

Exit the container and run sdk restart -x

when

nc command does not give any output.

then

Contact us.

when

nc command tells that the port is opened.

then

Exit the container. Check what process occupies the port by running the command, and make sure it is your IDE:

sudo lsof -nPi:9000 | grep LISTEN
