[RekhaDS]

Trying to deploy on Mac (macOS High Sierra)

Created a /db2 folder on the host, added /db2 mount point via Docker - Preferences

Ran the following -
docker run -i -t --privileged=true --name="db2inst1" -p 50000:50000 -v /db2:/home angoca/db2-instance

./createInstance
su - db2inst1
. ~db2inst1/sqllib/db2profile
su - db2inst1

db2inst1@ace6e0af1103:~$ db2start
SQL1042C An unexpected system error occurred.

db2 diag log shows -
