Terminating an Instance

When the user wishes to terminate an instance, they can do so within cfddfc using the terminate command. The particular instance to be terminated is selected either by launching the command within an OpenFOAM case directory that is attached to the instance (through a local .cfddfc file that contains the instance ID) with

cfddfc terminate

or by specifying an instance ID, e.g. aB1cD2eF, as an argument with the -key option, e.g.

cfddfc terminate -key aB1cD2e

Terminating Slave Instances of a Cluster

If the user wishes to terminate the slave instances of a cluster, they can do using the terminate command with the -cluster option as follows:

cfddfc terminate -cluster

Similarly to the previous, the instance ID of the master instance can be specified as an argument with the -key option.

Listing Instances

The user can find locate IDs by listing the instances registered in their ${HOME}/.cfddfc directory by

cfddfc list

which produces a table of essential connection details of each instance, e.g.

Code      InstanceId           PublicIpAddress  Region         Status   Label
aB1cD2eF  i-abc123def456ghi78  12.34.567.890    eu-central-1   ok       ---

The ID in column 1 can then be used to specify a particular instance using the -key option.

For a cluster of instances, the slave instances are listed following the master instance, with entries such as “=> cl 00”, e.g.

Code      InstanceId           PublicIpAddress  Region         Status   Label               
aB1cD2eF  i-abc123def456ghi78  12.34.567.890    eu-central-1   ok       ---
=> cl 00  i-jkl123mno456pqr78  ---              ---            ok       ---                 
=> cl 01  i-stu123vwx456yza78  ---              ---            ok       ---
