@nichlaes , one of the problems is that the default username is user1. This leads to problems for localhost and trial installation. The users are likely to use https://gitlab.com as authentication provider with user-level OAuth application. These users will have their own gitlab account. We need to make username as another argument to the single-script-install.sh. The changes are required in:

1. fileConfig.local.yml
2. fileConfig.trial.yml
3. docker run..... ml-workspace-user1 to change base URL
4. single-script.install.sh

Can you please look into this? Thanks.

printf "Remember to change foo.com and Gitlab OAuth details to your \
local settings in the following files.\n "
printf "1. %s/client/build/env.js\n " "$TOP_DIR"
printf "2. %s/servers/config/gateway/dynamic/fileConfig.yml\n " "$TOP_DIR"

The fileConfig.yml line is required only for trial config. This can be skipped for local config. Can you please put an if condition here to run the printf only in the trial config? Thanks.
