Bash

Summary

Item	Value
API name	bash
source OCI image	bash:5.2
per-job resource ceiling	1 vCPU, 256 MiB

The vCPU and RAM ceiling exists to prevent abuse; libkrun memory is elastic and the host only pays for what the guest touches.

Warmup

None: the official image already ships everything needed.

How the code is executed

The main file (the first in files) is executed with bash <file>. The available utilities are those in the official image; there is no network, so curl, wget and package managers reach nothing. Everything runs in a directory under /tmp (tmpfs), in a fresh VM destroyed at the end of the job.

Building the image

rc image build --stack bash

Example

curl -s http://127.0.0.1:8080/api/v1/run \
  -H 'Content-Type: application/json' \
  -d '{
    "language": "bash",
    "files": [
      {"name": "main.sh", "content": "read nome\necho \"olá, $nome\"\n"}
    ],
    "stdin": "mundo"
  }'

Expected stdout: olá, mundo.
