The setup mounts a single dedicated directory (~/.hermes-docker) into the container at /opt/data, keeping personal files, SSH keys, and other host resources outside the agent's reach while preserving persistent data across container recreation.", "body_md": "Giving an AI agent unrestricted access to your entire computer is probably not a great idea.\n\nEspecially when that agent can:\n\nThose capabilities are exactly what make Hermes Agent powerful.\n\nBut they also raise an important question:\n\n*Where should all of those actions actually run?*\n\nInstead of running Hermes Agent directly on my host machine, I decided to run it inside a Docker container and explicitly control what the agent can access.\n\nThe goal isn’t to make Hermes magically “secure” by putting it inside Docker.\n\nThe goal is much simpler:\n\nGive the agent access to what it needs, not your entire computer.\n\nIn this tutorial, I’ll walk through the complete setup.\n\nWe’ll configure:\n\n🎥 Prefer watching instead?\n\nI walk through the complete setup step-by-step in the video:\n\nWatch the full Hermes Agent Docker tutorial on YouTube →\n\nHermes isn’t just a chatbot.\n\nIt can interact with your environment and perform actions on your behalf.\n\nFor example, depending on the tools you enable, Hermes can work with files, execute terminal commands, install dependencies, use external services, and autonomously work through tasks.\n\nThat’s incredibly useful.\n\nBut if the agent runs directly on your main machine, you need to think carefully about what files, credentials, and system resources it can reach.\n\nThat’s where Docker becomes useful.\n\nInstead of letting Hermes operate directly across my host environment, I can put it inside a container and explicitly decide what crosses that boundary.\n\nThe architecture we’ll build looks roughly like this:\n\n```\n┌──────────────────── HOST MACHINE ────────────────────┐\n│

unless I explicitly expose something.\n\nOn macOS or Windows, install Docker Desktop and make sure the Docker engine is running.\n\nOn Linux, you can install Docker Engine using the instructions for your distribution.\n\nYou can verify Docker is available with:\n\n```\ndocker --version\n```\n\nOnce Docker is working, we can create an isolated environment for Hermes.\n\nFirst, create a directory specifically for the Dockerized Hermes instance:\n\n```\nmkdir -p ~/.hermes-docker\n```\n\nThis directory is important for two reasons.\n\nDocker containers are disposable.\n\nIf we remove and recreate the Hermes container, we don’t want to lose things like:\n\nWe’ll store those outside the container in ~/.hermes-docker.\n\nAnything inside this directory is intentionally available to Hermes.\n\nInstead of mounting my entire home directory, I’m giving the agent one dedicated location.\n\nThat distinction matters.\n\nNow we can start the official Hermes Agent image and launch the setup process:\n\n```\ndocker run --rm -it \\\n  -v ~/.hermes-docker:/opt/data \\\n  nousresearch/hermes-agent setup\n```\n\nThe most important part here is:\n\n```\n-v ~/.hermes-docker:/opt/data\n```\n\nThe -v option creates a bind mount between a directory on the host and a directory inside the container.\n\nThink of it like this:\n\n```\nHOST                           CONTAINER\n~/.hermes-docker   ───────▶   /opt/data\n```\n\nThe left side:\n\n```\n~/.hermes-docker\n```\n\nis the directory we just created on the host.\n\nThe right side:\n\n```\n/opt/data\n```\n\nis where that directory appears inside the Docker container.\n\nSo when Hermes saves configuration, sessions, memory, skills, or other persistent data under ***/opt/data***, those files are actually stored in ***~/.hermes-docker*** on the host.\n\nThat means we can destroy and recreate the container without losing the Hermes environment.\n\nMore importantly, we’re sharing one dedicated directory instead of the entire host filesystem.\n\nThe first run downloads the required Docker image and launches the Hermes setup wizard.\n\nFrom there, follow the normal Hermes configuration process.\n\nIn my setup, I:\n\nOnce setup finishes, the configuration is stored in our persistent directory.\n\nThat means future containers using the same mount can reuse it.\n\nNow we can start Hermes as a background container:\n\n```\ndocker run -d \\\n  --name hermes-docker \\\n  --restart unless-stopped \\\n  -v ~/.hermes-docker:/opt/data \\\n  -p 18642:8642 \\\n  -p 19119:9119 \\\n  -e HERMES_DASHBOARD=1 \\\n  nousresearch/hermes-agent gateway run\n```\n\nThere are a few important things happening here.\n\nRun in the background\n\n```\n-d\n```\n\nstarts the container in detached mode.\n\nGive the container a name\n\n```\n--name hermes-docker\n```\n\nmakes it easier to manage later:\n\n```\ndocker logs hermes-docker\ndocker stop hermes-docker\ndocker start hermes-docker\n```\n\nKeep the persistent directory\n\nWe’re mounting the same directory again:\n\n```\n-v ~/.hermes-docker:/opt/data\n```\n\nSo Hermes sees the configuration we created during setup.\n\nEnable the dashboard\n\n```\n-e HERMES_DASHBOARD=1\n```\n\nenables the Hermes Dashboard.\n\nYou’ll notice I’m using:\n\n```\n-p 18642:8642\n-p 19119:9119\n```\n\nDocker port mappings follow this pattern:\n\n```\nHOST_PORT:CONTAINER_PORT\n```\n\nSo:\n\n```\n18642 → 8642\n19119 → 9119\n```\n\nThe ports on the right are the ones Hermes uses inside the container.\n\nThe ports on the left are the ones exposed on my Mac.\n\nI’m deliberately using different host ports because I already have another Hermes instance running locally and don’t want the ports to clash.\n\nIf you’re running only the Docker instance, you can use the default ports 8642 and 9119 instead of 18642 and 19119.\n\nRun:\n\n```\ndocker ps\n```\n\nYou should see the hermes-docker container running.\n\nIf something isn’t working, one of the first places to look is the container logs:\n\n```\ndocker logs hermes-docker\n```\n\nThis becomes particularly useful when configuring the dashboard.\n\nWhen I initially opened the dashboard, it didn’t start correctly.\n\nInstead of hiding that part from the tutorial, I kept it in because it’s a useful troubleshooting example.\n\nChecking:\n\n```\ndocker logs hermes-docker\n```\n\nshowed that the dashboard needed an authentication provider.\n\nHermes provides authentication options for securing dashboard access.\n\nI configured mine using Nous Portal authentication.\n\nOnce authentication was configured, the dashboard started successfully.\n\nWith my port mapping, I can access it at:\n\n```\nlocalhost:19119\n```\n\nAnd now the Hermes Dashboard is running while Hermes itself remains inside the container.\n\nYou can also enter the running container directly:\n\n```\ndocker exec -it hermes-docker bash\n```\n\nThen start Hermes:\n\n```\nhermes\n```\n\nAt this point you’re interacting with Hermes from a terminal inside the Docker container, rather than running Hermes directly on the host.\n\nThat’s useful for testing.\n\nBut I don’t necessarily want to enter the container every time I want to use the agent.\n\nThere’s a better option.\n\nHermes Desktop can connect to the Gateway running inside our container.\n\nOpen Hermes Desktop and navigate to:\n\n```\nSettings → Gateway → Remote Gateway\n```\n\nThen configure it to use the Gateway exposed by your Docker container.\n\nIn my setup, that’s my url:\n\n```\nhttp://localhost:19119\n```\n\nAfter authenticating, save the configuration and reconnect.\n\nNow Hermes Desktop communicates with the Dockerized Hermes instance.\n\nSo from the user’s perspective, I still get the convenient desktop interface.\n\nBut the agent itself is operating inside the container.\n\nThis is probably the most important part of the tutorial.\n\nRunning an AI agent inside Docker does not automatically make it safe.\n\nDocker gives us a useful isolation boundary, but that boundary depends heavily on how the container is configured.\n\nFor example, imagine doing this:\n\n```\nHost machine\n      │\n      ▼\nEntire home directory\n      │\n      ▼\nDocker container\n      │\n      ▼\nHermes Agent\n```\n\nYou’ve technically containerized Hermes.\n\nBut you’ve also exposed a huge portion of your machine to it.\n\nThat’s not the setup I want.\n\nInstead:\n\n```\nHost machine\n      │\n      ├── Personal files       ❌\n      ├── SSH keys             ❌\n      ├── Other projects       ❌\n      ├── Docker socket        ❌\n      │\n      └── ~/.hermes-docker     ✅\n                │\n                ▼\n          Hermes Container\n```\n\nThe container should get access only to the resources required for the task.\n\nIf you mount your complete home directory into the container, Hermes could potentially access whatever the container’s permissions allow within that mount.\n\nThat might include personal files, source code, configuration files, credentials, or other sensitive data.\n\nThat’s why I’m using:\n\n```\n~/.hermes-docker\n```\n\nas a dedicated location instead.\n\nIf Hermes doesn’t need something, don’t expose it.\n\nThe same principle applies to API keys and tokens.\n\nOnly provide the credentials Hermes actually needs.\n\nAvoid unnecessarily exposing things such as:\n\n```\n~/.ssh\n```\n\nor unrelated cloud credentials and secrets.\n\nContainerization doesn’t help much if you put every sensitive credential inside the container anyway.\n\nAnother thing I’m deliberately not mounting is:\n\n```\n/var/run/docker.sock\n```\n\nGiving a container access to the host Docker daemon can dramatically expand what that container is capable of doing.\n\nFor an autonomous agent, that’s an especially important boundary to think about.\n\nIf Hermes doesn’t need to control Docker on the host, don’t give it that capability.\n\nThere’s another important limitation.\n\nAn AI agent can still encounter malicious or adversarial content.\n\nFor example, content from a webpage, repository, document, or other external source could attempt to manipulate the agent into performing unintended actions.\n\nPutting the agent inside Docker doesn’t eliminate that problem.\n\nThe difference is what happens after the agent attempts the action.\n\nIf Hermes only has access to:\n\n```\n/opt/data\n```\n\nthen we’ve limited the environment available to it.\n\nIf we’ve mounted our entire computer, exposed sensitive credentials, and given it access to the Docker daemon, the potential impact is very different.\n\nThat’s why I think containerization is better understood as blast-radius reduction, not a magic AI security solution.\n\nAs AI agents become increasingly capable, I think one traditional security principle becomes even more important:\n\nLeast privilege.\n\nAn agent should receive the minimum access required to complete its task.\n\nNot:\n\n```\nAgent\n  │\n  └── Everything on my computer\n```\n\nBut:\n\n```\nAgent\n  │\n  ├── Required files\n  ├── Required credentials\n  ├── Required network services\n  └── Required tools\n```\n\nNothing more.\n\nThis becomes increasingly important as agents gain longer-running autonomy, terminal access, browser access, external integrations, scheduled execution, and the ability to coordinate multiple tools.\n\nDocker is not the only way to isolate an autonomous agent.\n\nYou could also use:\n\nA VM generally provides a stronger isolation boundary than a standard application container because it virtualizes a larger portion of the environment.\n\nDocker, however, is lightweight and convenient for local development.\n\nFor my Hermes setup, it gives me a useful middle ground:\n\n```\nDirect Host Execution\n        ↓\nDocker Container\n        ↓\nVirtual Machine / Dedicated Environment\n```\n\nThe appropriate boundary ultimately depends on what capabilities you’re giving the agent and what resources it can access.\n\nAfter everything is configured, my setup looks roughly like this:\n\n```\n

EXPOSED\n```\n\nHermes still has the environment it needs to work.\n\nBut we’re being much more deliberate about what crosses the boundary.\n\nAutonomous AI agents are becoming capable of doing much more than generating text.\n\nThey’re increasingly able to:\n\n⚡ Execute commands\n\n🗂️ Manipulate files\n\n🌍 Interact with external systems\n\n🧰 Use specialized tools\n\n🔄 Run multi-step workflows autonomously\n\nThat’s exciting.\n\nBut the more capable the agent becomes, the more important its execution environment becomes.\n\nRunning Hermes Agent inside Docker doesn’t solve every security problem.\n\nIt does, however, give us a practical way to control what the agent can access and reduce the potential blast radius when something unexpected happens.\n\nThe rule I follow is simple:\n\nOnly give an AI agent access to what it actually needs.\n\nEverything else should stay outside the boundary.", "url":
