📖 Examples & Usage

You will be provided with a list of commands that you can use in your projects

The code with the commands will be on the way - link

🔌 Connect

The command to connect to the remote server

package main

import (
	"github.com/misha-ssh/kernel/pkg/connect"
	"github.com/misha-ssh/kernel/pkg/kernel"
)

func main() {
	connection := &connect.Connect{...}

	err := kernel.Connect(connection)
	if err != nil {
		panic(err)
	}
}

🔌 Download

The command to connect to the remote server

this command downloads the file from the server

package main

import (
	"github.com/misha-ssh/kernel/pkg/connect"
	"github.com/misha-ssh/kernel/pkg/kernel"
)

func main() {
	connection := &connect.Connect{...}

	remoteFile := "/remote.txt"
	localFile := "~/local.txt"

	err := kernel.Download(connection, remoteFile, localFile)
	if err != nil {
		panic(err)
	}
}

🔌 Upload

The command to connect to the remote server

this command is to upload a file to a remote server

package main

import (
	"github.com/misha-ssh/kernel/pkg/connect"
	"github.com/misha-ssh/kernel/pkg/kernel"
)

func main() {
	connection := &connect.Connect{...}

	remoteFile := "/upload.txt"
	localFile := "/absolute/path/your_local_file.txt"

	err := kernel.Upload(connection, localFile, remoteFile)
	if err != nil {
		panic(err)
	}
}

✍️ Create

The command to create a connection

this command saves the connection to a file and goes through the dependency initialization cycle

package main

import (
	"github.com/misha-ssh/kernel/pkg/connect"
	"github.com/misha-ssh/kernel/pkg/kernel"
)

func main() {
	connection := &connect.Connect{...}

	err := kernel.Create(connection)
	if err != nil {
		panic(err)
	}
}

🪄 Update

The command to update the connection

This command also updates the connection data if you need to resave the private key

package main

import (
	"github.com/misha-ssh/kernel/pkg/connect"
	"github.com/misha-ssh/kernel/pkg/kernel"
)

func main() {
	connection := &connect.Connect{...}

	err := kernel.Update(connection, "test")
	if err != nil {
		panic(err)
	}
}

🆑 Delete

The command to delete the connection

This command removes the connection from the file and also deletes the private key if it has been saved

package main

import (
	"github.com/misha-ssh/kernel/pkg/connect"
	"github.com/misha-ssh/kernel/pkg/kernel"
)

func main() {
	connection := &connect.Connect{...}

	err := kernel.Delete(connection)
	if err != nil {
		panic(err)
	}
}

📝 List

The command to get a list of connections

This command will list the connections from the previously created connections

package main

import (
	"fmt"

	"github.com/misha-ssh/kernel/pkg/kernel"
)

func main() {
	connections, err := kernel.List()
	if err != nil {
		panic(err)
	}

	fmt.Println(connections)
}

🖥 Struct Connection

This structure describes our connection

We pass this structure to the commands:

• Connect
• Create
• Update
• Delete

Description of fields:

• Alias - unique name (we use it when selecting an exception from the list and create unique connections to identify them)
• Login - the user's login on the remote device
• Password - if you have a password connection, then fill in this field, if with a key, then leave an empty line.
• Address - the address of the remote device
• Type - there is only one connection type so far - connect.TypeSSH
• CreatedAt - the creation time is filled in manually
• UpdatedAt - the update time is filled in manually
• SshOptions - this is a structure with additional fields for creating software - connect.TypeSSH
• Port - the port is filled in manually
• PrivateKey - the path along with the name of the private key

package main

import (
	"time"

	"github.com/misha-ssh/kernel/pkg/connect"
)

func main() {
	connection := &connect.Connect{
		Alias:     "test",
		Login:     "root",
		Password:  "password",
		Address:   "localhost",
		Type:      connect.TypeSSH,
		CreatedAt: time.Now().Format("2006.01.02 15:04:05"),
		UpdatedAt: time.Now().Format("2006.01.02 15:04:05"),
		SshOptions: &connect.SshOptions{
			Port:       22,
			PrivateKey: "/path/to/private/key",
		},
	}
}

🤖 Run ssh server

for local testing, you can raise your ssh servers - there are three types of them.

1. password connection

to run, write the command:

make up-ssh

to install and remove the server:

make down-ssh

Server accesses:

• login - root
• address - localhost
• password - password
• port - 22

1. connect with a private key

to run, write the command:

make up-ssh-key

to install and remove the server:

make down-ssh-key

Server accesses:

• login - root
• address - localhost
• private key - ./dockerkey
• port - 22

1. connecting via a non-standard port

to run, write the command:

make up-ssh-port

to install and remove the server:

make down-ssh-port

Server accesses:

• login - root
• address - localhost
• password - password
• port - 2222

🔖 Description variable

The variables that the application uses are located here:

• App values - link
• Config keys - link

App values (the values that are used in the application and also in the config):

• AppName - project name & project directory
• Theme - The theme is an application, there is no implementation at this stage.
• DirectionPrivateKeys - the name of the directory where the keys will be saved
• FilenameConnections - the name of the connection file
• FilenameConfig - the name of the file with the application configs
• NameServiceCryptKey - the names of the service that will store the private key for encryption
• TypeConsoleLogger - type for console logging
• TypeStorageLogger - the type for logging to a file
• TypeCombinedLogger - type for all types of logging

Config keys (these keys are located in the application configuration):

• Theme - stores the application's theme, in this case there is no implementation
• Logger - stores the type of application logging

🧪 Testing

You can run the command for testing after the step with local installation

The command to launch the linter:

make lint

Run Unit tests:

make tests

Run test coverage:

make test-coverage

Run test e2e:

make tests-integration
