We should have another step before this to update the existing image: docker-compose pull

If your policy is set on always pull like it is on our official docker-compose, it's not necessary

while I've my docker-based instance running, I tried just to run "docker-compose up -d" but it did not update the docker images, only when I run "docker-compose pull" then "docker-compose up -d" it updates the running instance. One more thing, I had also to run "docker-composer restart"

Running only "docker-compose up -d"

On the other hand, Running "docker-compose pull"

then "docker-compose up -d"

then "docker-compose restart"
