IONOSCTL CLI

---

Overview

IonosCTL is a tool to help you manage your Ionos Cloud resources directly from your terminal.

IonosCTL uses Cobra and Viper libraries in order to manage commands and options. Cobra is both a library for creating powerful modern command-line interface (CLI) applications as well as a program to generate applications and command files and it is used in many Go projects together with Viper library.

Getting started

Before you begin you will need to have signed-up for a Ionos Cloud account. The credentials you establish during sign-up will be used to authenticate against the Ionos Cloud API.

Installing ionosctl

Installing on Linux

You can install ionosctl using snap package manager:

snap install ionosctl

Installing on macOS

You can install ionosctl using the Homebrew package manager:

brew tap ionos-cloud/homebrew-ionos-cloud
brew install ionosctl

Installing on Windows

You can install ionosctl using the Scoop package manager:

scoop bucket add ionos-cloud https://github.com/ionos-cloud/scoop-bucket.git
scoop install ionos-cloud/ionosctl

Downloading a Release from Github

Check the Release Page and find the corresponding archive for your operating system and architecture. You can download the archive from your browser or you can follow the next steps:

# Check if /usr/local/bin is part of your PATH
echo $PATH

# Download and extract the binary (<version> is the full semantic version):
curl -sL https://github.com/ionos-cloud/ionosctl/releases/download/v<version>/ionosctl-<version>-linux-amd64.tar.gz | tar -xzv

# Move the binary somewhere in your $PATH:
sudo mv ionosctl /usr/local/bin

# Use the ionosctl CLI
ionosctl help

For Windows users, you can download the latest release available on Release Page, unzip it and follow this official guide that explains how to add tools to your PATH. The path that you need to add is the path to the folder where you unzipped the ionosctl release.

Building a local version(on a Linux machine)

If you have a Go environment (e.g. Go 1.18) configured, you can build and install the development version of ionosctl with:

git clone https://github.com/ionos-cloud/ionosctl.git

After cloning the repository, you can build ionosctl locally with:

make build

To install ionosctl locally, you can use:

make install

Note that the development version is a work-in-progress of a future stable release and can include bugs. Officially released versions will generally be more stable. Check the latest releases in the Release Page.

Dependencies: ionosctl uses Go Modules with vendoring.

On Windows, you just need to run the command

go install

from the folder where you cloned the ionosctl git.

Authenticating with Ionos Cloud

Before using ionosctl to perform any operations, you will need to set your credentials for IONOS Cloud account. The authentication mechanism is first checking the environment variables and if these are not set, it is checking if a configuration file exists and if the user has the right permissions for it.

You can provide your credentials:

• Using environment variables

You can set the environment variables for HTTP basic authentication:

export IONOS_USERNAME="username"
export IONOS_PASSWORD="password"

Or you can use token authentication:

export IONOS_TOKEN="token"

Also, you can overwrite the api endpoint: api.ionos.com via the --api-url global flag or via the following environment variable:

export IONOS_API_URL="api-url"

• Using login command

ionosctl login --user username --password password -v

The command can also be used without setting the --user and --password flags:

ionosctl login
Enter your username:
username
Enter your password:

You can also authenticate via --token flag exclusively:

ionosctl login --token $IONOS_TOKEN

After providing credentials, you will be notified if you logged in successfully or not:

Status: Authentication successful!

Error: 401 Unauthorized

Setting --api-url or IONOS_API_URL will overwrite the default value of https://api.ionos.com for subsequent requests.

After a successful authentication, you will no longer need to provide credentials unless you want to change them. By default, they will be stored in

• macOS: ${HOME}/Library/Application Support/ionosctl/config.json

• Linux: ${XDG_CONFIG_HOME}/ionosctl/config.json

• Windows: %APPDATA%\ionosctl\config.json

  and retrieved every time you will perform an action on your account.

Environment Variables

Environment Variable	Description
IONOS_USERNAME	Specify the username used to login, to authenticate against the IONOS Cloud API
IONOS_PASSWORD	Specify the password used to login, to authenticate against the IONOS Cloud API
IONOS_TOKEN	Specify the token used to login, if a token is being used instead of username and password
IONOS_API_URL	Specify the API URL. It will overwrite the API endpoint default value api.ionos.com. Note: the host URL does not contain the /cloudapi/v6 path, so it should not be included in the IONOS_API_URL environment variable
IONOS_LOG_LEVEL	Specify the Log Level used to log messages sent to the API. Possible values: Off, Debug, Trace
IONOS_PINNED_CERT	Specify the SHA-256 public fingerprint, enables certificate pinning which allows you to use the cli on servers that have a self-signed certificate

⚠️ Note: For IONOS_LOG_LEVEL we recommend you set to TRACE ONLY for debugging purposes. Disable it in your production environments because it can log sensitive data.
It logs the full request and response without encryption, even for an HTTPS call.
Verbose request and response logging can also significantly impact your application's performance.

Certificate pinning:

You can enable certificate pinning if you want to bypass the normal certificate checking procedure, by doing the following:

Set env variable IONOS_PINNED_CERT=<insert_sha256_public_fingerprint_here>

You can get the sha256 fingerprint most easily from the browser by inspecting the certificate.

Enabling Shell Auto-Completion

ionosctl provides completions for various shells, for both commands and flags. If you partially type a command or a flag and then press TAB, the rest of the command will be automatically filled in.

To enable auto-completion, you need to use ionosctl completion [shell], depending on the shell you are using.

ionosctl uses the latest release of Cobra framework, which supports by default completion with descriptions for commands and flags. To disable it, --no-descriptions flag is available.

Enabling Bash Shell Auto-Completion

To load completions for the current session, execute:

source <(ionosctl completion bash)

To make these changes permanent, append the above line to your .bashrc file and use:

source ~/.bashrc

By default, TAB key in Bash is bound to complete readline command. If you want to use menu-complete append the following line to .bashrc file:

bind 'TAB':menu-complete

You will need to start a new shell for this setup to take effect.

Enabling Fish Shell Auto-Completion

To load completions into the current shell execute:

ionosctl completion fish | source

In order to make the completions permanent execute once:

ionosctl completion fish > ~/.config/fish/completions/ionosctl.fish

Enabling Zsh Shell Auto-Completion

If shell completions are not already enabled for your environment, you need to enable them. Add the following line to your ~/.zshrc file:

autoload -Uz compinit; compinit

To load completions for each session execute the following commands:

mkdir -p ~/.config/ionosctl/completion/zsh
ionosctl completion zsh > ~/.config/ionosctl/completion/zsh/_ionosctl

Finally add the following line to your ~/.zshrcfile, before you call the compinit function:

fpath+=(~/.config/ionosctl/completion/zsh)

In the end your ~/.zshrc file should contain the following two lines in the order given here:

fpath+=(~/.config/ionosctl/completion/zsh)
#  ... anything else that needs to be done before compinit
autoload -Uz compinit; compinit
# ...

You will need to start a new shell for this setup to take effect. Note: ZSH completions require zsh 5.2 or newer.

Enabling PowerShell Auto-Completion

PowerShell supports three different completion modes:

• TabCompleteNext (default Windows style - on each key press the next option is displayed)
• Complete (works like Bash)
• MenuComplete (works like Zsh)

You set the mode with Set-PSReadLineKeyHandler -Key Tab -Function <mode>

Descriptions will only be supported for Complete and MenuComplete.

Follow the next steps to enable it:

To load completions for the current session, execute:

PS> ionosctl completion powershell | Out-String | Invoke-Expression

To load completions for every new session, run:

PS> ionosctl completion powershell > ionosctl.ps1

and source this file from your PowerShell profile or you can append the above line to your PowerShell profile file.

Regarding the PowerShell profile, you can follow the next steps:

• You need to find the PowerShell Profile path using the command $PROFILE and verify it is created with Test-Path $PROFILE.

• If the result of the previous command is false, the profile doesn’t exist you need to create one, so you can use the command New-Item -Type File -Force $PROFILE.

• Now, you created the profile and you can oopen file with a text editor and add the following line: . $PATH\ionosctl.ps1, where $PATH is absolute path to ionosctl.ps1 (for example . D:\ionoscloud\ionosctl.ps1)

In case you want more details, the profile creating steps are detailed in this link: https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_profiles?view=powershell-7.1

• If you get the following error:"path\Microsoft.PowerShell_profile.ps1" cannot be loaded because running scripts is disabled on this system, you can run the command Set-ExecutionPolicy RemoteSigned and restart the terminal. After you finish your work with ionosctl, you can run Set-ExecutionPolicy Restricted to disable running scripts.

You will need to start a new PowerShell for this setup to take effect.

Note: PowerShell completions require version 5.0 or above, which comes with Windows 10 and can be downloaded separately for Windows 7 or 8.1.

Output formatting

• Use the --output option

You can control the output format with the --output or -o option. IonosCTL supports JSON format for all commands output by specifying --output=json. By default, the output is set to text.

• Use the --quiet option

To redirect all the output to dev/null, except for error messages, you can use --quiet or -q option.

• Use the --force option

For deletion/removal commands, you will need to provide a confirmation to perform the action. To force the command to execute without a confirmation, you can use --force or -f option.

• Use the --all option

For deletion/removal commands, you can use the --all flag to delete all the resources. The command iterates through all the resources and deletes them. If an error happens, it will be displayed after the entire iteration is done.

• Use the --cols option

To obtain only a specific field/column, or a collection of columns on output, you can use the --cols option with the list of desired fields.

For example, if you want to print only the Datacenter ID and the Location for your existing Virtual Data Centers, you can use the following command:

ionosctl datacenter list --cols "DatacenterId,Location"
DatacenterId     Location
DATACENTER_ID1   us/ewr
DATACENTER_ID2   us/las
DATACENTER_ID3   us/las

Note: When using TAB in autocompletion, on --cols option on a specific resource, the available columns for that resource will be displayed.

• Use the --no-headers option

To skip printing the column headers in output format text.

• Use the --verbose option

You will see step-by-step process when running a command.

This flag can be used with any command(in general create, read, update, delete, but it's available also for the other specific command) of any resource.

• Use the --filters option

You can use the filters option for the majority of list commands, in order to filter the results based on properties or on metadata information. In order to set one or multiple filters, you must use the following format: --filters KEY1=VALUE1,KEY2=VALUE2. You can also use the --max-results or --order-by options.

Help Information

You can see all available options for each command, use:

ionosctl help [command]

ionosctl help [command] [command]

ionosctl [command] --help

ionosctl [command] -h

Testing

What Are We Testing?

The purpose of our unit tests is to ensure that properties set via flags are handled as expected before sending API Requests. The tests are integrated into GitHub Actions that run at every PR, commit and release.

We understand the importance of testing, and we put our best efforts to add integration tests as well.

How to Run Tests Locally

In order to run the tests locally, you can simply run:

make test

Examples

For each runnable command, use ionosctl [command] --help, ionosctl [command] -h or ionosctl help [command] or see the full reference documentation to see examples.

Uninstalling ionosctl

Local version

To uninstall a local version built with the steps from Installing Ionosctl, use:
