gitflow – Why deploy to DEV env?

You deploy to a development (QA) environment because you want people who are not developers to be able to view and explore the system with the changes. Further, you want those people to be able to do things that modify the data in ways that you wouldn’t want to do with staging (which usually shares a database with production).

Here’s a good post that explains the difference between development, QA, staging, and production. Note that development and QA often share databases as do staging and production. For purposes of this post, let’s define them that way.

If you skip having a deployed development environment (QA) and go straight to staging, then people who are not developers can’t test changes without risking data corruption in production. This is especially important when you have multiple developers or even multiple development teams whose software has to interact.

The QA (deployed development) environment allows non-developers to do things like add rows to the database (e.g. if you are building a shopping cart, you might add a product and place an order; if you are building a blog, you might make a post and comment on it; etc.). You don’t want to create fake data in production, at least not until you are really confident that the code is correct. Because then you have to clean them up later.

For example, you don’t want to actually ship your fake order or show your fake blog post on your blog. You might well test posting your next real blog post in the staging environment to verify that it really works (and if there’s a problem, you can switch to production to fix it while you go back to QA/development to do real testing).

You may notice that I have somewhat shifted terms on you. You asked why you deploy a DEV environment, and I am explaining why you would have a QA environment separate from staging. This is merely a matter of labels. A QA environment is a development environment that has been deployed. This separates it from localhost environments which are undeployed development environments often only accessible by the individual developer.

In early development, you may start with just a localhost environment. Later, you may create a deployed QA environment, where you can show your work to other people. Eventually, you create a staging environment and finally a production environment. Some might start with the production environment. But if you do that, you will find yourself having to clean your test data out before your initial deployment. Often times in professional work, all those things happen before you join the project.

We can call these stages different things. Whether it’s alpha, localhost, or undeployed development, it’s still the stage where a developer works. Whether it’s beta, QA, deployed development, development testing, or even staging, it’s the stage where others can view and explore changes. Whether it’s gamma, master, pre-production, staging, production testing, or whatever, it’s the stage where you do final acceptance testing before deploying changes visible to real users. And the final stage, whether we call it production, the real site, the public site, or anything else, is what our end users actually use.

It’s possible to skip some of these steps. You can edit the production software directly if you want. It’s riskier but possible (particularly if you are the only developer). But as we add more members to the team we find that we need more stages. Because we need developers to be able to test their own code (the first stage), non-developers to test new code (the second stage), to view the new code against the production data (the third stage), and a production where the code is used.

I’ve even seen localhost environments that worked with production data. These can be useful for debugging but increase the risk of data corruption. Or you can share your localhost environment with others and let them test on your computer — but then it’s hard to do development (because you may be editing the code as they are testing).

To get back to your original question, the reason why you deploy development code using development data is to allow people who are not you to test the software with your changes. In particular, this allows non-technical people to use the software with your changes and make test operations without risk of corrupting the production data.

sharepoint online – Programatically Deploy List Item Layout

Suppose we created a list with a custom list form layout. Now, I want to move this list to a different SharePoint tenant/site. How do I programmatically apply the custom form laout?

enter image description here

More details
I am using SharePoint PnP Provisioning templates to export and import lists. Unfortunately, it does not seem that the PnP Provisining template contains list item form’s laoyout.

Example of the Header JSON that I am trying to deploy programmatically:

{
    "elmType": "div",
    "attributes": {
        "class": "ms-borderColor-neutralTertiary"
    },
    "style": {

        "border-right-width": "0px",
        "border-style": "solid",
        "margin-bottom": "16px"
    },
    "children": [
        {
            "elmType": "div",
            "style": {
                "display": "flex",
                "box-sizing": "border-box",
                "align-items": "center"
            },
            "children": [
                {
                    "elmType": "div",

                        "title": "Details"
                    },
                    "style": {
                        "flex": "none",
                        "padding": "0px",

                        "height": "36px"
                    }
                }
            ]
        },
        {
            "elmType": "div",
            "attributes": {
                "class": "ms-fontColor-neutralSecondary ms-fontWeight-bold ms-fontSize-24"
            },
            "style": {
                "box-sizing": "border-box",
                "width": "100%",
                "text-align": "left",
                "padding": "21px 12px",
                "overflow": "hidden"
            },
            "children": [
                {
                    "elmType": "div",
                    "txtContent": "=' ' + [$Title]"
                }
            ]
        }
    ]
}

Is there a way to apply these JSON customizations using PowerShell PnP?

Make clean install of Ubuntu 20.04/Windows image it and deploy to 10 computers

I am currently working on new project, where I have to install a clean system (Ubuntu 20/ Windows 10). Install all needed software, make and image of these system (Ubuntu and Windows), then deploy on few other computer (10 to 15 computers). The computer hardware are almost the same. I know there a different tools for Ubuntu and Windows.

But I need few hint for this project.

Feel free to give me any proposition, I need direction.

ios – How can I securely deploy a configuration profile to an iPhone without another Apple device?

According to the documentation…

There are five ways to deploy configuration profiles:

As Apple Configurator is only available for macOS and both Over-the-Air Profile Delivery and MDM solutions are solutions for enterprises, you are probably left with e-mail message or a webpage.

You can of course also use any 3rd party app that offers some sort of file sharing/synchronization. But as you want to transfer sensitive information, make sure you use an app with end-to-end encryption, where you are the single owner of the encryption keys.

You can easily send a configuration profile via e-mail. As soon as you click on the attachment, it will be loaded and you can install it from the Settings app.

But as you want to transfer it securely, a simple e-mail won’t do it. Again, you need end-to-end encryption because the file will travel through the internet. You can achieve that by setting up S/MIME for your e-mail, for example. But I am not sure, if you can do it already as a consumer with the Apple mail app. You might need a 3rd party app for that.

It sounds like an overkill, but that can be done easily and securely with free open source tools and just your laptop. Steps you need:

  1. Interconnect your laptop and iPhone via WiFi (ad hoc network, no router needed, just the two devices)
  2. Setup a temporary HTTPS web server with Python to serve the configuration profile
  3. ???
  4. Profit: Access the configuration profile securely through Safari on your iPhone

This is how you can do it with a Windows laptop:

  1. Create a wireless ad hoc network. Use ipconfig afterwards to determine the IP address of your laptop for this network.

  2. Connect your iPhone to this network, as you would with any other WiFi.

  3. Create a self signed certificate that you will need for your web server. You can use OpenSSL for example. You already got that, if you have Git for Windows installed. You find it at <GIT_INSTALL_PATH>bin or <GIT_INSTALL_PATH>mingw64bin. To create that certificate, just execute:

     .openssl.exe req -new -newkey rsa:4096 -x509 -keyout localhost.pem -out localhost.pem -nodes
    
  4. Create the following folder structure to serve your configuration profile from:

     /
     └── www/
         ├── html/
         │   └── MyConfigProfile.mobileconfig
         └── localhost.pem
    
  5. Use html as your working directory and use Python 3 to start a HTTPS web server from there. Replace <IP> by the IP address you retrieved in step 1. You can also adjust the port address (2021), if you want:

     import http.server, ssl
    
     server_address = ('<IP>', 2021)
     httpd = http.server.HTTPServer(server_address, http.server.SimpleHTTPRequestHandler)
     httpd.socket = ssl.wrap_socket(httpd.socket, server_side=True, certfile='../localhost.pem', ssl_version=ssl.PROTOCOL_TLS)
     httpd.serve_forever()
    
  6. On your iPhone, open Safari and access https://<IP>:2021/MyConfigProfile.mobileconfig (replace <IP> by the IP address you retrieved in step 1). As you are using a self signed certificate, Safari cannot verify it and will complain. This is normally a security concern, but as you are the owner of both sides it is totally fine. To be 100% sure you can just compare the certificate shown on your iPhone with the one you generated on your laptop. You can then proceed to install the configuration profile.

How can I get my project to deploy to Firebase Hosting from Github?

I’m trying to deploy my NodeJS project to Firebase Hosting via Github. So far I have followed the steps here but when I navigate to the link that is created, I get to the ‘Firebase Hosting Setup Complete’.

What I see when I navigate to the link

I have set up hosting by running firebase init hosting and when setting up I said ‘yes’ to deploying from Github. The only part where what I did differs from the tutorial is I published what this command created to main instead of a new branch.

Could someone tell me how I can correct this step if this is the culprit or is there maybe another step after the ones listed in the tutorial to get the app live on Firebase?

javascript – Best practice to deploy Node.js Server-Client Code in WordPress?

I came across the following Github repository which works great when I install it on my Mac Node.js environment.

Github Link

What steps do I need to take to deploy this on a live WordPress site, as part of a page template in a child theme?

I know the necessary steps to deploy a vanilla JS (with pure client side JS/HTML code), but I’m struggling how to deploy the above code, specifically as it includes a server/client setup with socket.io and express.

Thanks!
