Add Docker's official GPG key: ```bash sudo install -m 0755 -d /etc/apt/keyrings curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg sudo chmod a+r /etc/apt/keyrings/docker.gpg ``` 3. Use the following command to set up the repository: ```bash echo \ "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \ "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \ sudo tee /etc/apt/sources.list.d/docker.list > /dev/null ``` 5. Update the package index again: ```bash sudo apt-get update ``` 6. Install Docker: ```bash sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin ``` 7. Start and enable the Docker service to run on boot: ```bash sudo systemctl start docker sudo systemctl enable docker ``` 8. Verify that Docker is installed and running: ```bash sudo docker --version ``` - Docker Compose more - https://docs.docker.com/compose/install - **Install Docker Compose:** 1. Download the latest version of Docker Compose: ```bash sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose ``` Replace `$(uname -s)-$(uname -m)` with the appropriate version for your system if needed. 2. Make the Docker Compose binary executable: ```bash sudo chmod +x /usr/local/bin/docker-compose ``` 3. Verify that Docker Compose is installed: ```bash docker-compose --version ``` - **Add Your User to the Docker Group (Not Recommended for Production)** - Add your user to the `docker` group: ```sh sudo chown $USER /var/run/docker.sock sudo usermod -aG docker $USER ``` Replace `$USER` with your actual username. - After adding your user to the group, you need to log out and then log back in for the changes to take effect. Alternatively, you can use the following command to activate the group membership without logging out: ```sh newgrp docker ``` - Verify that your user is now in the `docker` group: ```sh groups $USER ``` #### Git - Download Git - installation ```sh sudo apt-get install git ``` ```sh git config --global user.name "Your Name" ``` ```sh git config --global user.email "youremail@example.com" ``` #### Node ##### Node Version Manager (NVM) ###### **1. Install NVM:** First, you need to install NVM. Open your terminal and run the following commands: ```bash curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash ``` This command will download and run the NVM installation script. It will add NVM to your shell's configuration file (e.g., `~/.bashrc`, `~/.zshrc`, or `~/.profile`) and make it available for the current session. If you're using a different shell, make sure to adjust the configuration file accordingly. ###### **2. Close and Reopen Your Terminal:** After running the NVM installation script, close and reopen your terminal to ensure that the changes take effect. ###### **3. Verify NVM Installation:** To verify that NVM is installed correctly, you can run the following command: ```bash nvm --version ``` This should display the installed version of NVM. ###### **4. Install Node.js using NVM:** Now that NVM is installed, you can use it to install Node.js. You can install a specific version of Node.js or the latest LTS (Long-Term Support) version. For example, to install the latest LTS version, you can use the following command: ```bash nvm install --lts ``` To install a specific version of Node.js, replace `--lts` with the desired version, like `12.22.6`. You can check available versions using: ```bash nvm ls-remote ``` ###### **5. Use a Specific Node.js Version:** After installing Node.js, you can use it by setting it as the default version: ```bash nvm use ``` Replace `` with the desired Node.js version you want to use. For example: ```bash nvm use 12.22.6 ``` You can also set a default version for new terminals: ```bash nvm alias default ``` ###### **6. Verify Node.js Installation:** To verify that Node.js is installed correctly and to check the installed version, you can run: ```bash node -v ``` #### Golang ##### Installation 1. **Download Go:** - Download the Go tarball for your platform from the official [Go website](https://golang.org/dl/). 2. **Extract and Install Go:** ```sh tar -C ~/ -xzf go1.21.12.linux-amd64.tar.gz ``` 3. **Set up Go Environment Variables:** - Add the following lines to your shell configuration file (e.g., `~/.bashrc`, `~/.zshrc`, or `~/.profile`) to set the `$GOPATH` and add Go's binary directory to your `$PATH`: ```sh export GOPATH=$HOME/go export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin ``` - Reload your shell configuration file to apply the changes: ```sh source ~/.bashrc ``` 4. **Install GCC on Ubuntu:** ```sh sudo apt-get update sudo apt-get install build-essential ``` ##### Install Go Tools and UPX 1. **Install Go Tools:** - Run the following commands to install various Go tools: ```sh go install github.com/gordonklaus/ineffassign@latest go install github.com/client9/misspell/cmd/misspell@latest go install github.com/fzipp/gocyclo/cmd/gocyclo@latest go install golang.org/x/lint/golint@latest go install github.com/pwaller/goupx@latest go install github.com/swaggo/swag/cmd/swag@latest ``` 2. **Install Goreportcard** - Run the following commands: ```sh git clone https://github.com/gojp/goreportcard.git cd goreportcard make install go install ./cmd/goreportcard-cli goreportcard-cli ``` 3. **Install UPX:** - Install `xz-utils`: ```sh sudo apt update sudo apt install -y --no-install-recommends xz-utils ``` - Download and install UPX: ```sh curl -sSL https://git.io/vp6lP | sh sudo mv bin /usr/local ``` - Define the `UPX_URL` environment variable (replace `` with the actual version you want to download): ```sh export UPX_URL="https://github.com/upx/upx/releases/download/v/upx--amd64_linux.tar.xz" ``` - Download, extract, and install UPX: ```sh curl -sSL "$UPX_URL" -o upx.tar.xz sudo tar -xJvpf upx.tar.xz --strip-components=1 -C /usr/local/bin ``` - Clean up: ```sh sudo apt remove -y xz-utils sudo apt autoremove -y sudo apt clean sudo find /var/lib/apt/lists/ -type f -delete sudo find /var/cache/apt/archives/ -type f -delete rm upx.tar.xz ``` ##### Golang Version Manager (GVM) ###### Installation 1. **Install Prerequisites:** ```sh sudo apt-get update sudo apt-get install -y curl git mercurial make binutils bison gcc build-essential ``` 2. **Install GVM:** ```sh bash < <(curl -sSL https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer) ``` 3. **Source GVM Scripts:** - Add the following line to your shell configuration file (e.g., `~/.bashrc`, `~/.zshrc`, or `~/.profile`): ```sh source "$HOME/.gvm/scripts/gvm" ``` - Reload your shell configuration file to apply the changes: ```sh source ~/.bashrc ``` 4. **Install Go Versions Using GVM:** - To install a specific Go version, use the following command (replace `1.21.1` with the desired version): ```sh gvm install go1.21.1 ``` - Set the default Go version: ```sh gvm use go1.21.1 --default ``` #### PHP ##### PHP Version Manager (a2dismod, and a2enmod) ```sh Manual Switching From PHP 7.3 => PHP 8.1 Default PHP 7.3 is set on your system and you need to switch to PHP 8.1. Apache: $ sudo a2dismod php7.3 $ sudo a2enmod php8.1 $ sudo service apache2 restart Command Line: sudo update-alternatives --set php /usr/bin/php7.3 sudo update-alternatives --set phar /usr/bin/phar7.3 sudo update-alternatives --set phar.phar /usr/bin/phar.phar7.3 From PHP 8.1 => PHP 7.3 Default PHP 8.1 is set on your system and you need to switch to PHP 7.3.

Download and verify the Composer installer: Download Composer ```sh php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" php -r "if (hash_file('sha384', 'composer-setup.php') === 'YOUR_HASH_KEY') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;" ``` 2. Run the Composer installer: ```bash php composer-setup.php ``` 3. Remove the Composer setup file: ```bash php -r "unlink('composer-setup.php');" ``` 4. To make Composer globally available in your system, you can move it to a directory that's in your system's PATH. A common directory for global binaries is `/usr/local/bin`. You will need superuser privileges to move the Composer executable there. Use the following command: ```bash sudo mv composer.phar /usr/local/bin/composer ``` This command renames `composer.phar` (the downloaded Composer executable) to `composer` and moves it to `/usr/local/bin`, making it globally accessible. 5. Verify the installation by checking the Composer version: ```bash composer --version ``` This should display the installed Composer version. Now, Composer is installed and configured globally on your system, and you can use it for managing PHP dependencies in any directory. #### Java ##### Installing jEnv ```bash git clone https://github.com/jenv/jenv.git ~/.jenv ``` - Add jEnv to your shell startup file: - If you are using `bash`: ```bash echo 'export PATH="$HOME/.jenv/bin:$PATH"' >> ~/.bashrc echo 'eval "$(jenv init -)"' >> ~/.bashrc source ~/.bashrc ``` - If you are using `zsh`: ```bash echo 'export PATH="$HOME/.jenv/bin:$PATH"' >> ~/.zshrc echo 'eval "$(jenv init -)"' >> ~/.zshrc source ~/.zshrc ``` - Verify jEnv installation: ```bash jenv --version ``` ##### Installing Multiple JDK Versions - Install the required JDK versions: ```bash sudo apt install openjdk-11-jdk sudo apt install openjdk-19-jdk ``` - Add the JDK versions to jEnv: ```bash jenv add /usr/lib/jvm/java-11-openjdk-amd64/ jenv add /usr/lib/jvm/java-19-openjdk-amd64/ ``` - Verify the added JDK versions: ```bash jenv versions ``` ##### Setting the JDK Version - Set a global JDK version (default for all terminals): ```bash jenv global 11.0 ``` - Set a local JDK version (specific to a directory): ```bash cd ~/path-to-project jenv local 11.0 ``` - Verify the current JDK version: ```bash java -version ``` ------ ### Database Management {#database-environtment} #### Redis Insight (Free) - Redis Insight is a visualization and management tool for Redis.

Download Studio 3T ------ ### API Testing {#api-testing} ##### Postman - Installation ```sh sudo apt update sudo apt install snapd ``` ```sh sudo snap install postman ``` ##### SoapUI ------ ### Container Management {#container-management} #### Kitematic #### Kubernetes - Installation - ```sh curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl" ``` - Make `kubectl` Executable: After downloading the binary, you need to make it executable: ```sh chmod +x kubectl ``` - Move `kubectl` to a Usable Location: To make `kubectl` accessible system-wide, you can move it to a directory that's in your system's `PATH`. A common location is `/usr/local/bin`: ```sh sudo mv kubectl /usr/local/bin/ ``` - Verify `kubectl` Installation: ```sh kubectl version --client ``` - Command - **Manage Context** - Change Context ```sh kubectl config use-context ``` - List Context ```sh kubectl config get-contexts ``` - **Create or Update the Configuration File** - List Deployments You can use the `kubectl get` command to list Deployments in your cluster and find the name of the Deployment you want to update. Run the following command: ```sh kubectl get deployments -n ``` - Apply the Configuration File Use the `kubectl apply` command to apply the configuration file to your Kubernetes cluster. For example, if your configuration file is named `my-updated-service.yaml`, you would run: ```sh kubectl apply -f my-updated-service.yaml ``` This command will create or update the resources defined in the YAML file, depending on whether they already exist or not. Kubernetes will take care of the necessary updates. - Check the Status: After applying the configuration, you can check the status of the resources to ensure that the changes have been applied successfully. Use `kubectl get` to list the resources you modified, and observe their status. For example, if you updated a Deployment, you can check its status with: ```sh kubectl get deployment -n ``` - Rollout Verification (Optional): Depending on the type of change you made, you may need to verify that the rollout of the update is proceeding as expected. For example, if you made changes to a Deployment, you can monitor the rollout status with: ```sh kubectl rollout status deployment -n ``` - **Manage Pods** - List Running Pods To list all the running pods in your cluster, use the following command: ```sh kubectl get pods -n ``` - Check Logs for a Specific Pod To check the logs for a specific pod, use the `kubectl logs` command followed by the pod name: ```sh kubectl logs -n ``` If you want to view the logs continuously (like `tail -f`), you can use the `-f` flag: ```sh kubectl logs -f -n ``` - Manage Scaling - Scale Down Pods (Stop Services) Another way to stop services is by scaling down the replicas to zero. This effectively stops all instances of a service. For example, to scale down the `email-service` to zero replicas: ```sh kubectl scale deployment email-service --replicas=0 -n kasir-vending ``` This command sets the number of replicas for the `email-service` Deployment to zero, effectively stopping all instances of that service. - Scale Up Pods (Start Services) To start services again, you can scale up the replicas to the desired count. For example, to start the `email-service` with 2 replicas: ```sh kubectl scale deployment email-service --replicas=2 -n kasir-vending ``` This command sets the number of replicas for the `email-service` Deployment to 2, which will start two instances of the service. - Delete Pods (Stop Services) If you want to stop a specific service (pod), you can delete it using `kubectl`. For example, to stop the `email-service`, you can run: ```sh kubectl delete pod email-service-7dd6f49d8-jrh7f -n kasir-vending ``` This command will delete the specified pod. Kubernetes will automatically recreate it according to the desired state specified in your Deployment or StatefulSet configuration. - Setting up alias ```sh alias kubekasir='kubectl -n kasir-kita' ``` ------ ### Documentation {#documentation} #### Typora ------ ### Network Security {#network-security} #### Openvpn - Installation ```sh sudo apt update ``` ```sh sudo apt install openvpn ``` #### Teleport - Installation ```sh https://goteleport.com/download ``` - Login ```sh tsh login --proxy teleport.monstercode.net:443 --user=dikhi ``` ### Update History {#update-history} | No | Version | Revision Date | Revision Description | | ---- | ------- | ------------- | -------------------- | | 1 | 1.0 | Okt 07, 2023 | 1st Release |
