Murano Mini hackathon Plan
After this hackathon you’ll get familiar with OpenStack Murano and App Catalog, learn to install and deploy Murano Apps in the cloud, write your own application which deploys application in the cloud from Docker image picked by you.
Getting acquainted with Murano
Load application from the catalog Open apps.openstack.org. https://apps.openstack.org/ Look for Docker Nginx. Copy link to zip file with the package Import the application into the cloud Login to the cloud (address+name+password are provided by organizers) Menu item Murano\Manage\Package Definitions Button “Import Package” Import via url Check that packages of the app are downloaded (Murano\Manage\Package Defenitions) and images OS (Murano\Manage\Images)
Deploy the application Nginx Open menu Murano\Application Catalog\Environments Push button “Add New” and create new environment Add application DockerNginx “Container Host” - choose Docker Standalone Host and press Next “Instance flavor” - choose M2.Medium.4 “Instance Image” - choose Ubuntu Don’t change other fields Press Create Once again press Create Press “Deploy this environment” Wait for application to complete Go to Project/Compute/Instances and check that your application has started a new virtual machine for you Find address of the new virtual machine, open it in the browser Welcome to nginx!
Creating new application using Docker image Before passing on to the next stage of hackathon delete environment created before.
Choose the docker image based on which we want to make the application
Product being deployed Image name jenkins jenkins joomla 'gjong/apache-joomla'
you may choose another one after consulting the mentor Download an archive of the application to be modified Go to menu Murano/Package Definitions Find package Docker Nginx. Press Download Package. Download Unpack the Archive Modify the initial code Edit file DockerNginxSite.yaml, Rename into MyFirstApp.yaml In line №18 change class name into MyFirstApp
https://github.com/openstack/murano-apps/blob/stable/kilo/Docker/Applications/Nginx/package/Classes/DockerNginx.yaml#L18 In line №42 change the image name nginx into the one chosen by you In line №46 change port into 8080 In lines №61 and №63 change Nginx into the chosen by you image. These messages are displayed on installation Edit UI/ui.yaml In line 17 change com.example.docker.DockerNginx into com.example.docker.MyFirstApp
https://github.com/openstack/murano-apps/blob/stable/kilo/Docker/Applications/Nginx/package/UI/ui.yaml#L17 In line 34 change initial: DockerNginx into initial: MyFirstApp
Edit manifest.yaml Change package name into FullName: com.example.docker.MyFirstApp
Rename to MyFirstApp Change the description (поле Description) into the one you like In line №22 rename file name and class.example.docker.MyFirstApp: MyFirstApp.yaml
https://github.com/openstack/murano-apps/blob/stable/kilo/Docker/Applications/Nginx/package/manifest.yaml#L22 Optional - change the logo Pack updated file into archive Download the renewed application into the cloud Open Horizon, menu Murano/Package Definitions Press “Import Package” Select archive with updated files Next Next Create Check that your new package MyFirstApp is there in the list
Create environment and deploy application as we did it before in #2 “Deploy this environment” Wait for application to complete Go to Project/Compute/Instances, check that your app started new VM for you Find address of the new VM and open it in browser using port 8080 or 80 (depends on image you choose) You should see an interface of your new app
