Hi Experts,

I would like to change the color for the clusters like Tenancy, Compartment, VCN, OKE etc., Please refer below screenshots, Is that possible? If yes, can you pls guide me on that?

Output from Diagram tool:

Ideal output I would like to see:

Hi there, I'm enjoying using Diagrams.

But I've noticed a lot of the GCP icons appear to be outdated...

There is a new GCP architecture icons pack available at this link: https://cloud.google.com/icons Is it possible to update the library to use these?

Thanks, Soomin

This is a PR based on https://github.com/mingrammer/diagrams/pull/90 add custom AWS clusters (see examples/aws.png for reference)

I would love to here feedback before I will consider this to be ready.

C4 is a model for visualizing software architecture. It defines a common terminology and a few core diagrams at different abstraction levels. We primarily use the System Landscape, System Context and Container diagrams so I started with just the entities needed for those.

For a definition like this:

from diagrams import Diagram
from diagrams.c4 import Person, Container, Database, System, SystemBoundary, Relationship

graph_attr = {
    "splines": "spline",
}

with Diagram("Container diagram for Internet Banking System", direction="TB", graph_attr=graph_attr):
    customer = Person(
        name="Personal Banking Customer", description="A customer of the bank, with personal bank accounts."
    )

    with SystemBoundary("Internet Banking System"):
        webapp = Container(
            name="Web Application",
            technology="Java and Spring MVC",
            description="Delivers the static content and the Internet banking single page application.",
        )

        spa = Container(
            name="Single-Page Application",
            technology="Javascript and Angular",
            description="Provides all of the Internet banking functionality to customers via their web browser.",
        )

        mobileapp = Container(
            name="Mobile App",
            technology="Xamarin",
            description="Provides a limited subset of the Internet banking functionality to customers via their mobile device.",
        )

        api = Container(
            name="API Application",
            technology="Java and Spring MVC",
            description="Provides Internet banking functionality via a JSON/HTTPS API.",
        )

        database = Database(
            name="Database",
            technology="Oracle Database Schema",
            description="Stores user registration information, hashed authentication credentials, access logs, etc.",
        )

    email = System(name="E-mail System", description="The internal Microsoft Exchange e-mail system.", external=True)

    mainframe = System(
        name="Mainframe Banking System",
        description="Stores all of the core banking information about customers, accounts, transactions, etc.",
        external=True,
    )

    customer >> Relationship("Visits bigbank.com/ib using [HTTPS]") >> webapp
    customer >> Relationship("Views account balances, and makes payments using") >> [spa, mobileapp]
    webapp >> Relationship("Delivers to the customer's web browser") >> spa
    spa >> Relationship("Make API calls to [JSON/HTTPS]") >> api
    mobileapp >> Relationship("Make API calls to [JSON/HTTPS]") >> api

    api >> Relationship("reads from and writes to") >> database
    api >> Relationship("Sends email using [SMTP]") >> email
    api >> Relationship("Makes API calls to [XML/HTTPS]") >> mainframe
    customer << Relationship("Sends e-mails to") << email

It produces a diagram like this:

The implementation is a bit different from the other resources which are auto-generated based on images as far as I understand. If you'd prefer a different approach or would rather not have this upstream in diagrams, let me know! I also wasn't sure how to best integrate this in the documentation, but we could figure something out if this is a feature you'd like to see.

Original discussion in #489.

Hi there, Firstly, I love this project, thanks a lot! I am currently trying to create a diagram with labelled edges but the label position is incorrect.

For example, when building this example from the doc. You can compare the position of label collect (on the right of the image, between metric and replica) with the one of the documentation (which seems correct).

Tested with :

• Ubuntu 18.04 and dot - graphviz version 2.40.1 (20161225.0304)
• Ubuntu 20.04 and dot - graphviz version 2.43.0 (0)

In both configurations, here is what I get:

Image from the documentation:

Any clue?

First of all, Thanks a lot for this amazing innovative tool!! Great work!!

I am new to this tool and still learning it, so please forgive me if I am wrong.

Based on my research, there is no way to change the color of the node / cloud resources icon, lets say for OCI, it's always black, but Oracle is Red. Is that something that you guys can provide a resolution?

Thanks in advance for the help / support!!

Update existing GCP icons using updated official GCP icons: see https://cloud.google.com/icons.

Note, generic icons are updated with the corresponding new generic icon, except "ai-platform-data-labeling-service.png" since it now has its own unique icon.

Closes #554.

Thought it could be useful to have an image showing what the icon looks like in the docs. Also fixes #466

This is how the change looks:

I couldn't decide how to handle the white icons from OCI, so they are currently not visible against the white background, but they all have a black icon alternative next to them which is visible so that shouldn't be much of an issue. Can update this though if there any any suggestions for handling the white icons.

By the way, excellent project!

I've run the examples but the node labels are bad aligned. Maybe I'm using some incompatible graphviz version

• graphviz: 2.40.1-2
• diagrams: 0.2.1

Here a POC for a web generator.

Instructions: Go in docker directory. Run docker-compose up --build Wait to complete then open your browser http://0.0.0.0:5000/

It's an early version with bugs but basically you can build diagrams. Added fonts but only support Asian language CJK, and ascii + French (tested language). I mainly copy: http://webgraphviz.com/ :-)

Motivation

We sometimes do chatops with slack. We can potentially regard slack as a part of cloud architecture. So, it would be great to add the slack icon.

Comment

If it would be ok to add slack, I am not sure where it should be categorized.

This is a PR to replace #438 to fix up the merge conflicts. Most of the work has been done by others but I am willing to address any comments in this PR and keep it up to date to get it merged.

Not tested as #799 needs merged too.

Hi, I am getting the labels not very well aligned to the Arrows (Edge). Can you please point me in the direction to solve it?
