For the first example, we copy an Azure configuration file up to a Linux VM that is used to deploy automation. Because this file contains Azure API credentials, which include secrets, security is important. The encrypted tunnel provided by SSH protects the contents of the file. The following command copies the local. The admin user name on the Azure VM is azureuser. Substitute your own values in this command. For this example, we copy a directory of log files from the Linux VM down to your workstation.
What is docker? Why docker? In this case too, docker comes to the rescue. There is no requirement for a volume mount but it is recommended. Networking using the host network When the docker container is running it has its own localhost which is relative to its container and it has no awareness of localhost running on the host OS. How do we solve this problem? The above commands run our test at localhost Upload image.

Log on to the machine using the account for which you've prepared permissions as explained above. In your web browser, sign in to Azure Pipelines, and navigate to the Agent pools tab:.
Select the Default pool, select the Agents tab, and choose New agent. On the left pane, select the specific flavor. We offer x64 or ARM for most Linux distributions. We also offer a specific build for Red Hat Enterprise Linux 6. Follow the instructions on the page. Unpack the agent into the directory of your choice. Click Download agent. On the Get agent dialog box, click Linux. Make sure that the path to the directory contains no spaces because tools and scripts don't always properly escape spaces.
Browse to the latest release on GitHub. Make sure your server is configured to support the authentication method you want to use.
After you select Alternate you'll be prompted for your credentials. After you select Negotiate you'll be prompted for credentials. For guidance on whether to run the agent in interactive mode or as a service, see Agents: Interactive vs.
If you have been running the agent as a service, uninstall the service. To use your agent, run a job using the agent's pool. If you didn't choose a different pool, your agent will be in the Default pool.
For agents configured to run interactively, you can choose to have the agent accept only one job. To run in this configuration:. Agents in this mode will accept only one job and then spin down gracefully useful for running in Docker on a service like Azure Container Instances. If your agent is running on these operating systems you can run the agent as a systemd service:. We provide an example. This script will be generated after you configure the agent. We encourage you to review, and if needed, update the script before running it.
If you have a different distribution, or if you prefer other approaches, you can use whatever kind of service mechanism you prefer. See Service files. This command creates a service file that points to. This script sets up the environment more details below and starts the agents host. This variable is always equal to the name of the user who invoked the sudo command. If you need to update the variables for example, after installing some new software :.
The snapshot of the environment variables is stored in. You can also run your own instructions and commands to run when the service starts. For example, you could set up the environment or call scripts. For example, you have configured an agent see above with the name our-linux-agent. The service file will be either:. Azure Pipelines : the name of your organization. We provide the. But you can use whatever kind of service mechanism you prefer for example: initd or upstart.
You can use the template described above as to facilitate generating other kinds of service files. It's important to avoid situations in which the agent fails or become unusable because otherwise the agent can't stream pipeline logs or report pipeline status back to the server.
After you've done this, Linux reclaims system memory from pipeline job processes before reclaiming memory from the agent process. Learn how to configure cgroups and OOM score. When you configure an agent using the same name as an agent that already exists, you're asked if you want to replace the existing agent. If you answer Y , then make sure you remove the agent see below that you're replacing.
Otherwise, after a few minutes of conflicts, one of the agents will shut down. After you've removed the agent, you can configure it again. The agent can be set up from a script with no human intervention. You may have to backup an entire database on a secure share drive, or you may simply want to get a remote file to your system.
As a consequence, you want to transfer files , but you want to do it in a very secure and safe way. In this tutorial, we are going to see all the different ways to transfer files between hosts on Linux using either ftp, sftp, scp or rsync. The first way to transfer files on Linux is to use the ftp command.
It means that if someone were to track data or packets send over the network, it would be able to see what you are sending to remote hosts. In most cases, this is not something that you want for your file transfers, especially when they are done over Internet. However, we are still going to provide the syntax for the ftp command as it can be useful to use it for simplicity over local networks. In order to install new packages, you need to have sudo privileges on your Debian distribution.
When connecting, this is what you should see if you are connecting to a non-protected FTP server. You will be prompted to enter your password. If the credentials are correct, you should be able to login right into your FTP server. As you can see, the commands available are pretty much identical to the ones you would find on a standard Linux system. The local will be copied to your current working directory on the local machine, meaning the path from where you launched the ftp command in the first place.
With FTP, you can download files from your distant hosts but you are also able to upload files to your remote hosts. Your file should now be accessible on your remote host, in the home directory of the user you are using to transfer your files.
A more secure way to transfer files between two hosts is to use the sftp command.
