Pink Machine start

The powershell script has other parts in this

Start empty

Add to dashboard

remove the old ones keep it active

add to open shift

Looks like he installed on windows not the linux enviroment

Place we are trying to reach > While Andres outlines the estimation for his work!

Hassle and demo would be great on Linkedin > Nana created a course in a package!

AKS and nginx is there

AKS practical expose is there

Both are different > he used the windows on the kubernetes example which gives 2 sided examples to market on

Today i expect to have these

would trigger the create host

Manually get the diff of the linux install and fix it

ask your wishes

https://twitter.com/rifaterdemsahin/status/1782702096543818002

2 boxes to deliver

nginx would be used

Multiple controllers with one regfistry outside > delete them not to have cost!

Delete all with speed

Services and requirements

setting up the access is the key

redhat account

Lastpass fixed

More data

dns task automated

he is setting up his own version of ubuntu there

dns and connectivity of the host is also another project

PTR getting added

dont target that step >>> still the ubuntu is the one that he downloaded...and created!

he uses the bootstap for the inital machine name

My Steps >

Change the deployment to ubuntu latest version

Next Stage the vm gets created and the Openshift gets installed

haproxy to manage

see the oc command at the start is ok

after install practical tools are coming in Grafana video would be coming in

task 1 > update the ubuntu version 18 to 22 > ( done to 24 >>> UI loading takes too much time >> we need an image )

task 2 > install the bootstrapper

• library install > script

• dns *

task 3> Focus on the cluster! ( other role )

Openshift resolve the account

why empty ?

delete got triggered some how

4 day cycle

we need this to create resources with our latest image

To update your Azure ARM template to deploy the latest version of Ubuntu, you need to modify the imageReference section of the storageProfile within the Microsoft.Compute/virtualMachines resource definition. This section specifies the operating system image that the virtual machine will use.

Here's what you need to change:

• SKU: Ubuntu frequently updates its SKU names with the release of new versions. For instance, if you want to use the latest long-term support (LTS) version after Ubuntu 18.04, such as Ubuntu 20.04 LTS, you need to change the SKU to 20_04-lts-gen2.

• Publisher and Offer: Typically, for Ubuntu, the publisher is Canonical and the offer is UbuntuServer. These usually do not change unless Canonical changes their publishing details on Azure.

Here's an example of how the relevant part of your JSON template should look if you were updating to Ubuntu 20.04 LTS:

"storageProfile": {
"imageReference": {
"offer": "UbuntuServer",
"publisher": "Canonical",
"sku": "20_04-lts-gen2", // Change this line to the latest LTS version SKU
"version": "latest"
},
"osDisk": {
"createOption": "fromImage"
}
}

This adjustment will ensure that your deployment uses the Ubuntu 20.04 LTS image. If a newer LTS version is available and you want to use that, simply replace 20_04-lts-gen2 with the corresponding SKU of the new version, such as 22_04-lts-gen2 for Ubuntu 22.04 LTS.

Make sure to always check the Azure Marketplace or Canonical announcements for the latest available versions and their corresponding SKU names.

lets check the xrdp there now we can do this >

the client software is what we are looking for

It looks like you've provided an image of a script related to installing and setting up an OpenShift environment on a developer's host. Based on this image, you may be looking to generate a similar script.

Here's an outline of the steps that might be contained in such a script, according to the commands visible in your image:

• Install dos2unix: It's a utility to convert files from the DOS/Windows text format to the Unix text format.

• Get Installer: Use curl to download the OpenShift installer from the provided URL.

• Extract the Installer: Extract the downloaded tarball with tar xvf.

• Get OC client: Download the OpenShift client (oc) using curl.

• Extract the OC client: Extract the downloaded OpenShift client tarball.

• Create Install Directory: Make a directory, typically named for organizing installation-related files.

• Copy Configuration Files: Copy the OpenShift install configuration YAML files into the installation directory.

To recreate a full script for setting up OpenShift on a developer host, you would need to have more details, like specific URLs for downloads, which configuration files are needed, and how they should be configured.

If you can provide more details or additional parts of the script, I could help you construct a more complete version of the installation script.

than more on with xrdp to install there is they work ..this is going to be the second file in

Andres is quiet >>> time for him to come up with the numbers

maybe the xrdp is not running there well

I am able to login to the box

htop machine status

Practical sorters are there

xrdp is here

maybe it is out at starts?

To add a user to the sudo group on a Linux system, which essentially gives them superuser privileges, you would typically use the following command:

• Open your terminal.

• Type the following command to add the user "rifaterdemsahin" to the sudo group:

sudo usermod -aG sudo rifaterdemsahin

Here's what each part of the command does:

• sudo: Runs the command as a superuser.

• usermod: A utility to modify a user account.

• -aG: The -a is to append the user to the given group, and -G specifies the group.

• sudo: The name of the group to which the user will be added.

• rifaterdemsahin: The username of the user you want to add to the sudo group.

Make sure that you have administrative privileges to execute this command. After running it, the user "rifaterdemsahin" will have sudo access and can execute commands that require superuser permissions.

only sudo works maybde 24 is different

it says the packages are there

Looks like this part is working now > apt-get install xrdp -y

up it could be stuck

this looks like it is working

azure one looks like it is stuck

UI brings much more components than the past

if [ $? -ne 0 ]; then
echo "Failed to install ubuntu-desktop" 1>&2
exit 1
fi

sudo systemctl restart xrdp
if [ $? -ne 0 ]; then
echo "Failed to restart xrdp" 1>&2
exit 1
fi

Log the reboot action

echo "$(date "+%Y-%m-%d %H:%M:%S") - System is rebooting" | sudo tee -a /var/log/reboot.log > /dev/null

Reboot the system silently

sudo nohup shutdown -r now > /dev/null 2>&1 &

If you're experiencing a failure with the command echo "gnome-session" | sudo tee /etc/skel/.xsession > /dev/null on Ubuntu 24.04 due to permission issues, there are a few things to check and ensure for it to execute successfully:

• Sudo Privileges: Ensure the user executing the script has the necessary sudo privileges. This typically means the user should be able to execute commands with sudo without entering a password, or you must run the script in a context where the password can be entered if prompted.

• Filesystem Permissions: Make sure that the /etc/skel directory has the correct permissions. You can check the permissions with the following command:

ls -ld /etc/skel

Typically, the directory should be owned by root, and writable by the owner. If the permissions are incorrect, you can set them with:

sudo chown root:root /etc/skel
sudo chmod 755 /etc/skel

• Sudo Configuration: If the user has sudo access but cannot execute this specific command, check the sudoers file for any command-specific restrictions. You can view the sudoers file by running:

sudo visudo

Look for any lines that might limit the commands your user can run. Ensure there are no restrictive settings for the specific command or that the user isn’t limited to a subset of commands.

• SELinux or AppArmor Policies: Ubuntu uses AppArmor as a security module that could restrict actions even under sudo. If AppArmor is enforcing a policy that prevents writing to /etc/skel/.xsession, you might need to adjust the policy. Check the status and logs of AppArmor with:

sudo aa-status
sudo dmesg | grep apparmor

Adjusting AppArmor policies can be complex, so it's essential to understand the implications of changes you make.

• Debugging the Command: Run the command outside the script to check its output and error messages directly in your terminal. This might provide additional clues:

echo "gnome-session" | sudo tee /etc/skel/.xsession

By ensuring these aspects are correctly set up, the command should execute without permission issues. If problems persist after checking and adjusting these settings, you may need to look deeper into system logs or specific configurations unique to your setup.

feels stuck

much longer install time is there
