To store our files, we will use nextcloud

kubectl create namespace cyberlocker

kubectl create secret generic nextcloud --namespace cyberlocker \
  --from-literal=admin-username=caretaker \
  --from-literal=admin-password=$(head -c 512 /dev/urandom | LC_CTYPE=C tr -cd 'a-zA-Z0-9' | head -c 64) \
  --from-literal=serverinfo_token=$(head -c 512 /dev/urandom | LC_CTYPE=C tr -cd 'a-zA-Z0-9' | head -c 64) \
  --from-literal=smtp_username= \
  --from-literal=smtp_password= \
  --from-literal=smtp_host=

kubectl create secret generic nextcloud-postgresql-database --namespace cyberlocker \
  --from-literal=postgres-password=$(head -c 512 /dev/urandom | LC_CTYPE=C tr -cd 'a-zA-Z0-9' | head -c 64) \
  --from-literal=password=$(head -c 512 /dev/urandom | LC_CTYPE=C tr -cd 'a-zA-Z0-9' | head -c 64)

kubectl create secret generic nextcloud-redis --namespace cyberlocker \
  --from-literal=redis-password=$(head -c 512 /dev/urandom | LC_CTYPE=C tr -cd 'a-zA-Z0-9' | head -c 64)
