Below is the command to create a plugable database. Another way is to create through dbca.
CREATE PLUGGABLE DATABASE orclpdb ADMIN USER pdbadm IDENTIFIED BY password
STORAGE (MAXSIZE 2G)
DEFAULT TABLESPACE testpdb
DATAFILE '/disk1/oracle/dbs/orclpdb/sales01.dbf' SIZE 250M AUTOEXTEND ON
PATH_PREFIX = '/disk1/oracle/dbs/orclpdb/'
FILE_NAME_CONVERT = ('/disk1/oracle/dbs/pdbseed/', '/disk1/oracle/dbs/orclpdb/');
