Lambda ssh to ec2

I have created a Paramiko library layer and attached it to the function, lambda ssh to ec2. This function works perfectly when I run it locally in VSCode. The key file is stored in the same folder as the code. The version of the Paramiko library is the same both locally and in the Lambda layer.

With the addition of the Scheduled Events feature, you can now set up AWS Lambda to invoke your code on a regular, scheduled basis. This is especially useful for scheduling tasks e. You will trigger this shell script through a Lambda function written in Python 2. Cron is indeed simple and well understood, which makes it a very popular tool for running scheduled operations. However, there are many architectural benefits that make scheduled Lambda functions and custom scripts a better choice in certain scenarios:. While there are many ways of achieving the above benefits, scheduled Lambda functions are an easy-to-use option in your toolkit.

AWS Lambda lets you run arbitrary code without worrying about provisioning servers. This is a very powerful way to control access to your EC2 instances. Using one or more Lambda functions as a proxy allows you to provide an HTTP based interface to existing functionality. You can also make it more secure. While traditional SSH access requires a user account with privileges managed by something like sudo , the unfortunate truth is that the attack surface of a shell account is very large. By using a proxy, you are limiting the commands that can be run to the subset you define. Finally, AWS IAM allows fine grained access control; if you have two functions one of which restarts a process and the other of which reads process status, you can grant different roles and users different abilities to call these functions based on time, user or even IP address. Finally, like any good adapter pattern , a Lambda proxy has minimum impact on the proxied resource. The application can continue to run without being modified; all you have to do is add a user identity with sufficient permissions that the Lambda can assume as well as assure network and shell access. This alternative does require installation of an agent on each instance. While the example below uses node, any of the other Lambda runtimes would work, as long as the language, or a library for the language, has support for SSH.

Note that the EC2 instances in a private subnet can access the internet unless you lock down outgoing network access. Deepak Patil lg

Despite double-checking the key file, username, security group permissions, and ensuring that everything is in order, I am still encountering an Authentication Error. But, since your message is ""Authentication failed. This will clear potential key-related issues. Also, I would suggest to activate paramiko's logging at DEBUG level to better see what's happening when connection is initiated: you may have a routing and sec group issue between your Lambda and your EC2. I resolved the issue. The problem was related to the versioning of the paramiko library and its dependencies.

Because we are using the simple-ssh module, we need to deploy as a zip file. I resolved the issue. Comment Share. A good answer clearly answers the question and provides constructive feedback and encourages professional growth in the question asker. Anyone who can access the Lambda zip file will be able to get the private key and will have the ability to SSH in to the EC2 instances security groups and network limits notwithstanding. This is especially useful for scheduling tasks e. You can also make it more secure. However, I am facing an issue. The command cmd is hardcoded. I highly recommend you not do this. Caution: To keep your keys secure, make sure no other IAM users or roles, other than intended users, have access to this S3 bucket. Why would you want to do this? On the Select blueprint page, type cron in the search box.

Understand and analyze setup environment, availability, cost comparison, performance and more. Cloud Foundry Foundation, a non-profit organization that overlooks the open-source cloud computing projects, conducted a global survey recently consisting of users. AWS Lambda is becoming popular for serverless application development since they enable an organization to develop scalable software and applications than server-based applications, for example, EC2.

This is both cumbersome and time-consuming. The Configure Function page appears. This is especially useful for scheduling tasks e. Install Virtualenv on your local Linux machine or an EC2 instance. This alternative does require installation of an agent on each instance. AWS Lambda logs all requests handled by your function and automatically stores logs generated by your code using Amazon CloudWatch Logs. While the example below uses node, any of the other Lambda runtimes would work, as long as the language, or a library for the language, has support for SSH. Intelligent scheduling: With scheduled Lambda functions, you can add custom logic to you abstracted job scheduler. This brings additional flexibility to your systems without requiring substantial changes to the underlying operating environment. All you need to do now is upload your key and script file to S3 buckets and then you are ready to run the example. Note that the EC2 instances in a private subnet can access the internet unless you lock down outgoing network access.
