Description of problem
For some reason, my system is quite slow and container creation is taking more than 30sec for postgres to be up and running.
When cloning a database, the data is not copied. When creating a database, I need to manually enter the container and run CREATE DATABASE test_new_db
By adding a bigger value (60s for instance), my container is fully functional.
- if ! suppress_output "$DOCKER_BIN" container run "${LINK_CONTAINER_DOCKER_ARGS[@]}" "$PLUGIN_WAIT_IMAGE" -c "$network_alias:$PLUGIN_DATASTORE_WAIT_PORT"; then
+ if ! suppress_output "$DOCKER_BIN" container run "${LINK_CONTAINER_DOCKER_ARGS[@]}" "$PLUGIN_WAIT_IMAGE" -c "$network_alias:$PLUGIN_DATASTORE_WAIT_PORT" -t 60; then

Success. You can now start the database server using:
pg_ctl -D /var/lib/postgresql/data -l logfile start
initdb: hint: You can change this by editing pg_hba.conf or using the option -A, or --auth-local and --auth-host, the next time you run initdb.

How (deb/make) and where (AWS, VirtualBox, physical, etc.) was Dokku installed?:
deb, self hosted on bare metal
Additional information
A plugin setting to allow a bigger value for the timeout would solve the issue I think ?
