dotnet mvc on Oracle ACCS

In this article, I’m going to briefly walk through how to create and deploy a .net mvc sample app in Oracle Application Container Cloud Service.

Assumptions:

  • you have an Oracle Cloud account, it can be the promotion trial account
  • you have dotnet core installed on your local machine – I’m using dotnet 2.0.0 on MacOS
  • you have the corresponding editor / tools, e.g. I’m using VS Code.
  1. Launch VS Code and open the embedded Terminal. Alternatively, you can also use your favorite editor and/or the OS Terminal (in Windows, that will be the Command Window).

  2. Create and goto (mkdir/cd)  your desire folder and create the mvc project – I will call the project accssample:

mkdir accssample
cd accssample
dotnet new mvc

Screen Shot 2018-03-25 at 11.04.30 AM.png

  1. Open Program.cs file of the project, add .UseContextRoot( )  and .UseUrls( ) in the CreateDefaultBuilder
.UseContentRoot(Directory.GetCurrentDirectory())

.UseUrls("http://*:"+ Environment.GetEnvironmentVariable("PORT"))
Your program will looks like this

Remember to save the changes.

  1. Use the terminal to update the project dependencies and create a debug build for local testing.
dotnet restore
dotnet build

Screen Shot 2018-03-25 at 11.25.17 AM.png

  1. Test the program locally
export PORT=8080
dotnet run

 

Screen Shot 2018-03-25 at 2.07.15 PM

Open a browser and navigate to http://localhost:8080 to test the app locally

Screen Shot 2018-03-25 at 2.08.12 PM

 

  1. Once we are happy with the app, we can create the release build. We will need to publish to Linux release for ACCS.
dotnet publish -c Release -r linux-x64

Screen Shot 2018-03-25 at 11.42.10 AM

  1. For ACCS to start the program, we will create 2 more files in the distribution (i.e. linux-x64) folder
start.sh
manifest.json

Right click the linux-x64 folder and choose new file, name the first file as manifest.json

Screen Shot 2018-03-25 at 11.43.51 AM

Screen Shot 2018-03-25 at 11.44.11 AM

  1. Enter the contents of manifest and remember to save it. For more info about ACCS manifest, please refer to ACCS documentation https://docs.oracle.com/en/cloud/paas/app-container-cloud/dvcjv/creating-meta-data-files.html

Screen Shot 2018-03-25 at 11.50.31 AM

  1. Repeat the same for the start.sh

Screen Shot 2018-03-25 at 11.50.42 AM

  1. In the terminal window, zip the release, start.sh and manifest.
cd bin/Release/netcoreapp2.0/linux-x64/
zip -rq accssample.zip manifest.json start.sh publish

Screen Shot 2018-03-25 at 12.01.27 PM

  1. The application is now ready to deploy to ACCS. We can either use Web GUI, CLI or REST API to deploy the app.

I’ve a small shell script to execute curl to send REST to deploy the app. I also have a deployment.json file to control the memory and number of instance of the app. The deployment json looks like this

{
        "memory":"1G",
        "instances":"1"
}

this is what I did to deploy the app to ACCS,

 

Screen Shot 2018-03-25 at 1.22.10 PM

and this is what my script looks like – what I actually do is

  • create a storage container
  • put my the zip file in the container
  • create an ACCS app from zip (in storage container)

Screen Shot 2018-03-25 at 2.42.55 PM

  1. We can double check the application deployment from ACCS WebUI (or using CLI / REST API)

Screen Shot 2018-03-25 at 2.48.01 PM

  1. Our sample app is now up and running in ACCS.

SonarQube with Oracle Developer Cloud

Got a question from my sales colleague whether DevCS supports SonarQube. The quick answer is “yes” and I’m going to briefly describe how to do it. I’m going to create a SonarQube VM via Bitnami in OCI Classic and scan the spring-boot example during the maven build process.

Part A – SonarQube

  1. The first step is the create the SonarQube VM in OCI Classic. Just like what we’ve talk about previously, we can use the Bitnami portal to provision the VM. Login to Bitnami and navigate to the Launchpad for Oracle Cloud.

Go to the Library tab and search for SonarQube. Click the Lauch button to create the VM.

Screen Shot 2018-03-20 at 9.22.03 AM

  1. Pick the corresponding OCI Classic Cloud Account, please refer the previous post about the details of setting up Cloud Account in Bitnami. Choose the desired disk size and server size. In this example, we will use Oracle Linux as the OS of the VM. When ready, just click to Create button.

Screen Shot 2018-03-20 at 9.23.48 AM

  1. Wait for a while for your VM to get provisioned. In the provision screen, you can get the login information (username/password) of SonarQube, as well as the SSH key to access the VM.

Screen Shot 2018-03-20 at 9.49.50 AM

  1. Once SonarQube is ready, you can either
  • click the [GO TO APPLICATION] button
  • manually use a browser to navigate to http[s]://[ip-address-of-vm]

to access SonarQube (web interface).

  1. Login SonarQube with credential you got in the previous step (i.e. default username is admin)

Screen Shot 2018-03-20 at 9.52.29 AM

  1. The first time you access SonarQube, the tutorial / wizard will guide you through some initial steps. We will to create a token (for details of using SonarQube, you can visit their website).

Provide a name for the token and click [Generate]

Screen Shot 2018-03-20 at 9.50.02 AM

Copy the token value, as you will need it for your maven step. When ready, click [Continue]

Screen Shot 2018-03-20 at 9.50.14 AM

  1. It will then ask which programming language you need to scan. In our example, we will just click [Java].

Screen Shot 2018-03-20 at 9.50.41 AM

For Java, we can select whether we use maven or gradle for the build process. For our example, we will use maven.

Screen Shot 2018-03-20 at 9.50.55 AM

The required mvn command will be displayed in the right hand side (you can also copy this command for future reference). Click [Finish this tutorial]

Screen Shot 2018-03-20 at 9.51.36 AM

Part B – Developer Cloud

8.  In our build job, we will need to add sonar:sonar as part of the maven goal. We will also need to provide the sonar server url and token we got in part A. When the build executes, this maven step will post the project source code to SonarQube for code scan.

Screen Shot 2018-03-21 at 12.58.05 PM

  1. Here comes the sample (console) output of the build step – the snippet of code being scanned.

Screen Shot 2018-03-21 at 3.29.04 PM

  1. You should be able to view the scan report in SonarQube

Jenkins on Oracle BMCS

Last time, I posted the installation of GitLab. So, we have the Git…. what’s next?

A lot of people suggest CI – continuous integration. Thus, I’m going to talk about Jenkins in this post.

ASSUMPTION / PREREQUISITE:

  • we have a BMCS subscription
  • we already create a Linux VM or BM, have the VCN and Internet Gateway setup

We can put Jenkins in the same VM/BM as GitLab, or we can use another VM to run Jenkins.

Steps

  1. Similar to GitLab, the first step here is to get the Jenkins installation binary. We can navigate to Oracle Cloud Marketplace
    https://cloudmarketplace.oracle.com/marketplace/en_US/listing/16132843
    for details
    Screen Shot 2017-08-02 at 9.43.18 AM
  2. Just click the [Get App>] button and follow the instruction. It will guide us throughout the Jenkins installation process.
  3. Actually, what we need to do is to ssh to the VM/BM to download and install Jenkins. In the VM/BM use wget to download Jenkins.
    Screen Shot 2017-08-02 at 10.43.51 AM
  4. The download will take a while. wait for the download to complete. Then change the file permission to so that we can run the installer.
    Screen Shot 2017-08-02 at 10.43.32 AM
  5. In our example, we will install Jenkins in the same VM/BM as GitLab. We will use non-privilliged port to run Jenkins and run it with oracle user.
    Screen Shot 2017-08-02 at 10.45.02 AM
  6. The installer will install Gradle along with Jenkins.
    – Answer [Y] and press [Enter] when it ask for Gradle.
    – Answer [Y] and press [Enter] when it ask you to confirm.
    Screen Shot 2017-08-02 at 10.45.57 AM
  7. Next, the installer will prompt you for installation folder. Enter your desired folder. In our example, we will put it under /u01
    Screen Shot 2017-08-02 at 10.46.53 AM
  8. Enter your desired Jenkins SUPER ADMINISTRATION username and password
    Screen Shot 2017-08-02 at 10.47.56 AM
  9. The installer will then ask you for Apache and Tomcat port to be used for Jenkins. You can just keep the default values.
    Screen Shot 2017-08-02 at 10.48.40 AM
  10. Enter [Y] for the last confirmation and wait for the installation to complete.
    Screen Shot 2017-08-02 at 10.48.55 AM
  11. Jenkins should starts automatically after the installation.

How to start / stop / restart Jenkins

Just navigate to the target folder and use the ctlcscript, e.g.

[oracle@kmean jenkins-2.60.2-0]$ ./ctlscripts.sh start

 

or

[oracle@kmean jenkins-2.60.2-0]$ ./ctlscripts.sh stop

How to access / navigate / login to Jenkins

It is simple, just use a browser and go to
http://your-vm-bm-ip-fqdn:apache-port/
e.g. http://jenkins.mydomain.com:8080/

Screen Shot 2017-08-02 at 10.56.41 AM

Click the [Access Jenkins] link and login with the username/password we’ve entered during installation.

Setting up GitLab in Oracle BMCS

Not sure if you heard something like this 🙂

  • Github is good but I want my own private repo.
  • Well I know you have DevCS, but I want something I can have full control…

Today, I’m going to talk about Bring Your Own Git – I’m going to use GitLab CE as my example.

Assumption / Prerequisite:

  • we have a BMCS subscription
  • we already created a Linux VM or BM, have the VCN and Internet Gateway setup

Steps

  1. The first step is to get the GitLab CE, we can navigate to Oracle Cloud Marketplace
    https://cloudmarketplace.oracle.com/marketplace/en_US/listing/16076589
    for details
    Screen Shot 2017-08-01 at 8.41.35 AM
  2. Just click the [Get App>] button and follow the instructions. It will guide us how to download and install GitLab CE for Oracle BMCS.
  3. Actually, what we need is to ssh to the VM/BM to download and install GitLab. In the VM/BM, use wget to download GitLab 
      wget -O gitlab-linux-installer.run \
    https://bitnami.com/stack/gitlab/download_latest/linux-x64

    Screen Shot 2017-08-01 at 10.06.06 AM

  4. The download will take a while, wait for the download to complete
    Screen Shot 2017-08-01 at 10.11.52 AM
  5. Change the file permission so that we can run the installer. Then, we can run the installer. If we want to have GitLab running on privileged port, i.e. 80/443, we will need to run the installer as root (or sudo).
    Screen Shot 2017-08-01 at 10.12.27 AM
  6. The installer will ask us to confirm the installation. Simply answer Y and press enter.
    Screen Shot 2017-08-01 at 10.13.04 AM
  7. Next, the install will ask us to setup the super admin account password for GitLab. Enter the desired password and press enter. Of course, we will need to enter the desired password the second time as confirmation. After that, we will be prompted to continue again – answer Y and press enter at this point.
    Screen Shot 2017-08-01 at 10.14.45 AM
  8. Installation will take a while. Just wait for the completion.
    Screen Shot 2017-08-01 at 10.15.02 AM
  9.  Once we see installation complete, we are ready to rock and roll.

How to start / stop the GitLab stack?

To start GitLab, use the command

[oracle@kmean ~]$ sudo /opt/bitnami/ctlscript.sh start

To stop GitLab, use the command

[oracle@kmean ~]$ sudo /opt/bitnami/ctlscript.sh stop

To check the status, use the command
Screen Shot 2017-08-01 at 3.36.39 PM

How to configure / re-configure GitLab?

We will need to edit the config file(s) – we will cover this topic later. BTW, you probably NEED to do reconfigure BEFORE the first run 🙂 just use the command

[root@kmean ~]# gitlab-ctl reconfigure

or sudo gitlab-ctl reconfigure command if you are not running as root user.
Screen Shot 2017-08-01 at 11.59.59 AM
again, reconfigure might take a while
Screen Shot 2017-08-01 at 12.00.19 PM
also, the first time to do reconfigure, we will need to set the GitLab root password again.

How to access my new Git?

It is simple, just use the browse to navigate to the host. I’ll recommend you use SSL port 🙂 https://{your-vm-bm-ip-fqdn}/

Screen Shot 2017-08-01 at 3.47.01 PM

I will cover more about custom configurations, custom SSL/TLS cert, GitLab integration, DevOps in BMCS later 🙂 please stay tuned.
