limitations when creating docker container installation

[rcruicks]

trying to install demo live system in bluemix container environment (docker)

install-system.sh will fail when trying to create and manipulate swap settings -- script option to bypass swapfile section?

install-system.sh will fail trying to install fuse device from openjdk-associated packages -- apt-get install will work if it includes "--no-install-recommends"

hardcoding of database name to openeyes in numerous locations prevents creating mysql database in cloud-managed service (these pre-assign dbname) - container with remote database would require options on install-oe.sh to provide -u -p -h -P and -D overrides

just found that cloud mysql server (in multitenant service) does not allow superuser GRANT privileges with default access account -- ideally would like to set username/password to cloud service credentials

it seems to be able to do swapon/swapoff and mknod operations in docker, host admin privileges are required; this can lead to other problems, and are often made unavailable.
a check for running within a docker container could automate bypass of the failing instructions

if grep "cpu:/docker" /proc/1/cgroup >/dev/null;
then
enable swapfile stuff
enable fuse-related stuff
