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 {#dev-env-git} Download Git ##### installation {#dev-env-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 {#dev-env-node} ##### Node Version Manager (NVM) {#dev-env-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 {#dev-env-golang} ##### Installation {#dev-env-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 {#dev-env-golang-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 "$UPX_URL" -o upx.tar.xz sudo tar -xJvpf upx.tar.xz --strip-components=1 -C /usr/local/bin ``` - Clean up: ```sh sudo apt remove -y xz-utils sudo apt autoremove -y sudo apt clean sudo find /var/lib/apt/lists/ -type f -delete sudo find /var/cache/apt/archives/ -type f -delete rm upx.tar.xz ``` ##### Golang Version Manager (GVM) {#dev-env-golang-install-gvm} ###### Installation 1. **Install Prerequisites:** ```sh sudo apt-get update sudo apt-get install -y curl git mercurial make binutils bison gcc build-essential ``` 2. **Install GVM:** ```sh bash < <(curl -sSL https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer) ``` 3. **Source GVM Scripts:** - Add the following line to your shell configuration file (e.g., `~/.bashrc`, `~/.zshrc`, or `~/.profile`): ```sh source "$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 {#dev-env-php} ##### Installation {#dev-env-php-installation} - **Apache** ```sh sudo apt install apache2 ``` - **Add the ondrej/php Repository:** - To add the repository, run the following command: ```sh sudo add-apt-repository ppa:ondrej/php ``` - After running this command, you may need to update your package list again: ```sh sudo apt update ``` - **Install PHP 7.3:** - You can install PHP 7.3 with the following command: ```sh sudo apt install php7.3 ``` - Additionally, you can install commonly used PHP extensions for PHP 7.3 by running: ```sh sudo apt install php7.3-common php7.3-mysql php7.3-xml php7.3-xmlrpc php7.3-curl php7.3-gd php7.3-imagick php7.3-cli php7.3-dev php7.3-imap php7.3-mbstring php7.3-opcache php7.3-soap php7.3-zip php7.3-pgsql php7.3-mysql ``` - **Install PHP 8.2:** - You can install PHP 8.2 with the following command: ```sh sudo apt install php8.2 ``` - Similarly, you can install commonly used PHP extensions for PHP 8.1: ```sh sudo apt install php8.2-common php8.2-mysql php8.2-xml php8.2-xmlrpc php8.2-curl php8.2-gd php8.2-imagick php8.2-cli php8.2-dev php8.2-imap php8.2-mbstring php8.2-opcache php8.2-soap php8.2-zip php8.2-pgsql php8.2-mysql ``` - **Install Composer:** 1. 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. ##### PHP Version Manager (a2dismod, and a2enmod) {#dev-env-php-pvm} Manual switching between PHP versions (e.g., PHP 7.3 and PHP 8.1) can be done using the steps below: 1. **Switch from PHP 7.3 to PHP 8.1** - **Apache Configuration** 1.

Download Studio 3T ------ ### API Testing {#api-testing} #### Postman {#api-testing-postman} - Installation ```sh sudo apt update sudo apt install snapd ``` ```sh sudo snap install postman ``` #### SoapUI {#api-testing-soap-ui} ------ ### Container Management {#container-management} #### Kitematic {#container-management-kitematic} #### Kubernetes {#container-management-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 {#docs-typora} ------ ### Network Security {#network-security} #### Openvpn {#network-security-openvpn} - Installation ```sh sudo apt update ``` ```sh sudo apt install openvpn ``` #### Teleport {#network-security-teleport} - Installation ```sh https://goteleport.com/download ``` - Login ```sh tsh login --proxy teleport.monstercode.net:443 --user=dikhi ```
