Intro


This blog post continues a series of publications about the Installation of different SAP Systems in Hyperscalers

About Cloud Trends



Cloud computing is a new technology trend. A lot of guidelines about SAP in SAP Cloud Platform, Amazon AWS, Google GCP, and Microsoft Azure. For example a new openSAP course:


In this step-by-step guideline, you know about another newbie among Cloud Providers – about Mail.ru Cloud Solution (MCS for short).  Competition among cloud services is a good thing for customers! Prices are down – Quality is up.




About Mail.ru and Mail.ru Cloud Solution (MCS)


Mail.ru (“Russian Yahoo”)  is a multinational corporation specializing in Internet-related products and services, including social networks, e-mail services, eCommerce, navigation, mobile applications, MMO games, and online advertising. Mail.ru Cloud Solution (cloud service was started in 2018) is a suite of cloud solutions that makes it fast and safe to get as much computing power as you need on a pay-as-you-go model. You access this computing power over the internet. MCS offers different categories of cloud resources, such as virtual machines, block storage, Kubernetes, databases, etc. You can manage resources in each category using the web-based console.



About Docker containers


Docker is a product that uses OS-level virtualization to deliver software in packages called containers.Containers are isolated from one another and bundle their own software, libraries, and configuration files; they can communicate with each other through well-defined channels. Today a lot of software (from SAP SE too) distributed in pre-configuring docker containers via special repositories such as DockerHub.



Tooling (mandatory, and optional)



We can use some free programs for our installation and usage scenario.

PuTTYgen – Public/Private keys generator (optional)

Putty - SSH client (optional)


and

mobaXterm – Next-generation SSH client and SFTP manager (optional) -


SAP GUI - GUI software for accessing to SAP system (mandatory, See Step 9)



Resolution.



Step 1. DockerHub registration

DockerHub registration mandatory

Register in DockerHub - https://hub.docker.com/


Step 2. MCS registration

Register / Log-in in MCS  – https://mcs.mail.ru/en/

Credit card mandatory. After the first payment (approx. $14) you received an additional $40 on your balance as a welcome gift. This is enough to try the service and run SAP in Docker container without any additional charges from your credit card.


Step 3. Create an instance


Step 3.1. MCS web console

Get started with the MCS web console.

Select a Cloud computing - Virtual machines - Create an instance and creating a Linux VM.


Step 3.2. Instance configuration

Provide a Name, Type of virtual machine, Disk size, and Operating system

For our purposes:

Name - SAP ABAP

Type - 4CPU, 16GB RAM

Disk size - 160 GB

Operating system - Linux Centos







Step 3.3. Network settings for an instance

Chose a default network settings






Step 3.4. Setting up a backup for an instance

Chose a default setting for an instance backup






Step 4.  SSH connection to an instance (optional)

Create SSH connection for an instance


Step 4.1. Pem file

After instance was successfully created you can find  *.pem file in the Downloads folder of your browser







Step 4.2. Convert .pem file into .ppk file 


We must convert .pem file into .ppk file.

Open PuTTYgen

Under Type of key to generate, choose RSA and then

Choose Load. By default, PuTTYgen displays only file with the extension .ppk. To locate your .pem file, choose the option to display files of all types and provide your .pem file from Step 4.1

Add key passphrase (optional)

Save private key








Step 4.3. Firewall settings


Create rule group in "Virtual networks. Firewall settings"  section of MCS console

Rule group name (For example - AllowSSH)







Allow Inbound/Outbound  TCP-traffic on port 22

and allow Inbound/Outbound  TCP-traffic on port 3200 (for SAP GUI)








Goto Virtual machines section. Networks. Editing a connection. Replace firewall settings. "default" group on your custom "AllowSSH" group






Step 4.3. External IP

Find external IP in "Virtual machines" section of MCS console






Step 4.4. SSH connection in Putty

Create SSH connection in the Putty client with ip from Step 4.3 and add a private key (ppk-file from Step 4.2) in the Auth section






Step 4.5. Import Putty configuration 

Import Putty configuration to the mobaXterm







Step 5.  Console connection to an instance (Alternative)


Virtual machines section. Console tab

The "Set password" button (with an arrow on the screenshot)

Provide a password for default embedded user "centos"

The "Open in a new window" button

Working with an instance in a separate browser window







Step 6. Docker installation


In your Console / SSH session


Check Available Package Updates



sudo yum check-update


Download and install the last stable Docker version


curl -fsSL https://get.docker.com/ | sh


Add  centos user to the docker user group


sudo usermod -aG docker centos


Start Docker daemon


sudo systemctl start docker


Check daemon status


sudo systemctl status docker






Step 7. ABAP Platform. Developer Edition. Installation


To be able to pull the image you must run the command docker login at first.


docker login






Pull an image from a DockerHub registry


docker pull store/saplabs/abaptrial:1909





Step 8. ABAP Platform. Developer Edition. Start container.


Start the docker container


docker run --stop-timeout 3600 -i --name a4h -h vhcala4hci -p 3200:3200 -p 3300:3300 -p 8443:8443 -p 30213:30213 -p 50000:50000 -p 50001:50001 store/saplabs/abaptrial:1909 -agree-to-sap-license


Check result. It must be: All services have been started


Troubleshooting:







Resolution:


Set parameters



sudo sysctl vm.max_map_count=2147483647

sudo sysctl fs.file-max=20000000

sudo sysctl fs.aio-max-nr=18446744073709551615


Keep this setting after reboot



sudo echo "vm.max_map_count=2147483647" >> /etc/sysctl.conf

sudo echo "fs.file-max=20000000" >> /etc/sysctl.conf

sudo echo "fs.aio-max-nr=18446744073709551615"  >> /etc/sysctl.conf


Find and copy container id



docker inspect a4h






Remove  container


docker container rm XXX

where XXX - container id


and try to start again.

If the error persists, you can try using the argument -skip-limits-check



docker run --stop-timeout 3600 -i --name a4h -h vhcala4hci -p 3200:3200 -p 3300:3300 -p 8443:8443 -p 30213:30213 -p 50000:50000 -p 50001:50001 store/saplabs/abaptrial:1909  -agree-to-sap-license -skip-limits-check

Step 9. SAP GUI Installation


Download SAP GUI for Windows from SAP Developers Portal


Simple registration required


Unrar it

Run installation process







Step 10. License installation

Step 10.1. Generate license


Run command


docker exec -it a4h /usr/local/bin/asabap_license_update

and retrieve Hardware Key








Generate license for  A4H - SAP NetWeaver AS ABAP 7.4 and above (Linux / SAP HANA)








Download license file - A4H_Multiple.txt



Step 10.2. Upload license to Linux machine

Sftp client embedded into mobaXterm

Drug and drop license file (A4H_Multiple.txt) into /tmp directory on Linux machine






Step 10.4. Upload license to container




Reside license into the docker container:



docker cp /tmp/A4H_Multiple.txt a4h:/opt/sap/ASABAP_license


Step 10.2. Run update script



docker exec -it a4h /usr/local/bin/asabap_license_update






Step 11. ABAP Platform. Developer Edition. Exploring.


Create new connection

N.B. We allow port 3200 on Step 4.3






Log in with embedded DEVELOPER user credentials:



Client: 001

User: DEVELOPER

Password: Ldtf5432
