Adjustments of clusters

[Olgoetz]

Hi,

First of all, thanks a lot for this tool. I really like it a lot. At the momen, I am struggling with a proper alignment of nodes:

from diagrams.aws.compute import ECS, EKS, Lambda, EC2, AutoScaling
from diagrams.aws.database import RDS
from diagrams.aws.storage import S3
from diagrams.aws.network import ELB, InternetGateway

with Diagram("Terraform Enterprise", show=True):

    with Cluster("AWS Cloud"):
        source = ELB("Application Load Balancer")
        with Cluster("Availability Zone 1"):
            with Cluster("Private Subnet"): 
                tfe_1 = EC2("Terraform Enterprise")
                rds_1= RDS("Postgre Main")

            with Cluster("Public Subnet"):
                squid_1 = EC2("Squid Proxy")

        with Cluster("Availability Zone 2"):

            with Cluster("Public Subnet"):
                squid_2 = EC2("Squid Proxy")

            with Cluster("Private Subnet"):
                rds_2= RDS("Postgre Standby")
                tfe_2 = EC2("Terraform Enterprise")

        source >> [tfe_1, tfe_2]
        tfe_1 >> squid_1
        tfe_2 >> squid_2
        [squid_1, squid_2] >> InternetGateway("IGW")

The result is:

By chaning the position of the RDS nodes, it should be fine. But I do not know how?

The best I could do is use a blank Cluster as a spacer.

However, with the current code base, the background colors of the Clusters are set automatically based on their nested depth so there is no way to make the spacer-Cluster completely invisible without changing the code.

                tfe_1 >> squid_1

    [squid_1, squid_2] >> InternetGateway("IGW")
    source = ELB("Application\nLoad\nBalancer")
    source >> [tfe_1, tfe_2]

Slight modification of above to merge the blank Cluster with the "Public Subnet" Cluster.

with Diagram("Terraform Enterprise", show=False) as diag:

    with Cluster("AWS Cloud"):

        with Cluster("Availability\nZone 1"):
            with Cluster("Private Subnet"): 
                rds_1 = RDS("Postgre\nMain")
                tfe_1 = EC2("Terraform\nEnterprise")

            with Cluster("Public Subnet"):
                rds_1 - Edge(penwidth="0.0") - Custom("","transparent.png")
                squid_1 = EC2("Squid Proxy")
                tfe_1 >> squid_1

        with Cluster("Availability\nZone 2"):
            with Cluster("Private\nSubnet"):
                tfe_2 = EC2("Terraform \nEnterprise")
                rds_2= RDS("Postgre\nStandby")

            with Cluster("Public Subnet"):
                squid_2 = EC2("Squid Proxy")
                tfe_2 >> squid_2
                rds_2 - Edge(penwidth="0.0") - Custom("","transparent.png")

    [squid_1, squid_2] >> InternetGateway("IGW")
    source = ELB("Application\nLoad\nBalancer")
    source >> [tfe_1, tfe_2]
