[GCLOUD_WIDE_FLAG ...]
DESCRIPTION
Generate a SSH script for a Database Migration Service migration job.
Generate a script for a Database Migration Service migration job, to
configure Reverse SSH tunnel connectivity with a bastion host on a Compute
Engine VM instance. You can use an existing VM instance or create a new VM
for this purpose.
Copy the generated script and run it in bash from a machine that has:
▪ The gcloud command-line tool installed.
▪ Access to your source database.
▪ Access to the existing bastion VM, or permissions and access to the
Cloud Compute API if creating a new bastion VM. Make sure this machine
is available during the entire migration.
Running the script will set up the SSH tunnel on the VM you selected and
will establish connectivity between the source database and the Cloud SQL
instance. Find additional information here
(https://cloud.google.com/database-migration/docs/mysql/configure-connectivity-reverse-ssh-tunnel).
EXAMPLES
To generate a SSH script for a Database Migration Service migration job
with vm creation config, run:
To generate an SSH script with bastion VM instance creation:
$ gcloud database-migration migration-jobs generate-ssh-script \
my-migration-job --vm=sample-vm --vm-port=1111 \
my-migration-job --vm=vm1 --vm-port=1111 \
--vm-machine-type=n1-standard-1 --vm-zone-create=us-central1-a \
--subnet=sample-subnet --region=us-central1
To generate a SSH script for a Database Migration Service migration job
with vm selection config, run:
To generate an SSH script with an existing bastion VM instance:
$ gcloud database-migration migration-jobs generate-ssh-script \
my-migration-job --vm=sample-vm --vm-port=1111 \
my-migration-job --vm=vm1 --vm-port=1111 \
--vm-zone=us-central1-a --region=us-central1
