Teleport 7.0 introduces a dependency on
libelf.so.1
which was not previously present in Teleport container images, resulting in an error when Teleport attempts to run inside the container:My best guess is that this dependency was introduced due to the addition of
clang
for compiling BPF bytecode as per #6027.The following Docker images are unusable due to this bug:
quay.io/gravitational/teleport:7.0.0-beta.1
quay.io/gravitational/teleport-ent:7.0.0-beta.1
quay.io/gravitational/teleport-ent:7.0.0-beta.1-fips
