Error: map error: failed to create map AYA_LOG_BUF with code -1

[kaplanelad]

Hey there,

I'm currently working on running an example project on an Ubuntu Docker container.
After installing all the dependencies, the following command works perfectly fine:

cargo xtask build-ebpf

However, when I attempt to run the project using:

RUST_LOG=debug cargo xtask run

I encounter the following error:

[2023-07-27T10:20:49Z DEBUG demo] remove limit on locked memory failed, ret is: -1
[2023-07-27T10:20:49Z DEBUG aya::bpf] BPF Feature Detection: Features {
        bpf_name: false,
        bpf_probe_read_kernel: false,
        bpf_perf_link: false,
        bpf_global_data: false,
        bpf_cookie: false,
        btf: None,
    }
Error: map error: failed to create map `AYA_LOG_BUF` with code -1

Caused by:
    0: failed to create map `AYA_LOG_BUF` with code -1
    1: Operation not permitted (os error 1)

I would really appreciate it if someone could assist me in resolving this issue. Thanks in advance for your help!

Received an answer on Discord! To run the Docker container correctly, we need to include the following flags: --privileged --security-opt seccomp=unconfined

I'll create a pull request with an example in the book project. Thanks, @vadorovsky, for your help!
