| Look at |
| https://skia.googlesource.com/buildbot/+/master/site_config/slave_hosts_cfg.py |
| to see what the roles of the instances are going to be. |
| The following are a few examples: |
| - VM_INSTANCE_OS=Windows SKIA_BOT_MACHINE_TYPE=n1-standard-16 \ |
| VM_BOT_COUNT_START=16 VM_BOT_COUNT_END=19 bash vm_create_setup_instances.sh |
| |
| - VM_IS_ANDROID_MERGE=1 VM_INSTANCE_OS=Linux \ |
| SKIA_BOT_MACHINE_TYPE=n1-standard-16 VM_BOT_COUNT_START=14 \ |
| VM_BOT_COUNT_END=14 bash vm_create_persistent_disks.sh |
| - VM_IS_ANDROID_MERGE=1 VM_INSTANCE_OS=Linux \ |
| SKIA_BOT_MACHINE_TYPE=n1-standard-16 VM_BOT_COUNT_START=14 \ |
| VM_BOT_COUNT_END=14 bash vm_create_setup_instances.sh |
| |
| Access instances |
| ================ |
