# Limitations

**What frameworks/languages does mirrord support?**

mirrord works by [hooking libc](https://metalbear.com/blog/mirrord-internals-hooking-libc-functions-in-rust-and-fixing-bugs/), so it should work with any language/framework that uses libc (vast majority).

This includes: Rust, Node, Python, Java, Kotlin, Ruby, and others (most languages use libc).

mirrord also supports [Go](https://metalbear.com/blog/hooking-go-from-rust-hitchhikers-guide-to-the-go-laxy/), which doesn't use libc

**Does mirrord support clusters with a service mesh like Istio or Linkerd?**

Yes, mirrord works exactly the same way with and without a service mesh installed.

**Does mirrord support OpenShift?**

Yes, mirrord works with OpenShift. However, OpenShift usually ships with a default security policy that doesn't let mirrord create pods. To fix this, you would need to tweak your `scc` settings - more information [here](https://docs.openshift.com/container-platform/3.11/admin_guide/manage_scc.html). If you'd rather keep the default security policies, we recommend trying out [mirrord for Teams](/mirrord/docs/getting-started/installing-mirrord/operator.md).

**Does mirrord support binaries that are statically compiled? (Linux)**

No, mirrord needs to be able to leverage dynamic linking in order to work. This means static binaries are not supported.

To check a binary, you can use the `file <FILE_NAME>` command - dynamically linked binaries will look like this:

```bash
marvin@heart-of-gold:~$ file /usr/bin/ls
/usr/bin/ls: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=36b86f957a1be53733633d184c3a3354f3fc7b12, for GNU/Linux 3.2.0, stripped
```

And static binaries will look like this:

```bash
marvin@heart-of-gold:~/MetalBear$ file some_static_binary 
some_static_binary: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically linked, BuildID[sha1]=2e1eda62d5f755377435c009e856cd7b9836734e, for GNU/Linux 3.2.0, not stripped
```

Sometimes, Go is statically compiled by default, so it's important to check and compile dynamically if necessary. See [this section in Common Issues](/mirrord/docs/faq/troubleshooting/common-issues.md#ive-run-my-program-with-mirrord-but-it-seems-to-have-no-effect) for more info.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://metalbear.com/mirrord/docs/faq/limitations.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
