Limitations
What are the limitations to using mirrord?
What frameworks/languages does mirrord support?
mirrord works by hooking libc, 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, 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. If you'd rather keep the default security policies, we recommend trying out mirrord for Teams.
Does mirrord support Teleport, Tailscale, or other secure cluster access tools?
Yes, and there's nothing to configure.
mirrord reaches your cluster entirely through the Kubernetes API, using the same kubeconfig kubectl uses. That covers everything it does: the mirrord Operator is exposed as a Kubernetes APIService, and the connection to the mirrord agent runs over Kubernetes port forwarding. mirrord never opens a network path of its own.
If kubectl works through your access provider, mirrord works through it too. Customers run mirrord behind Teleport and Tailscale today.
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:
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, strippedAnd static binaries will look like this:
Sometimes, Go is statically compiled by default, so it's important to check and compile dynamically if necessary. See this section in Common Issues for more info.
