GitLab Runner Docker执行器config.toml特性标志配置报错求助

问题根源 #

你遇到的TOML类型错误，是因为ARTIFACT_COMPRESSION_LEVEL和CACHE_COMPRESSION_LEVEL这两个配置项不属于[runners.feature_flags]区块。这个区块仅用于存放布尔类型的特性开关（均以FF_为前缀），而这两个配置是字符串类型的参数，强行放入会导致TOML解析器尝试将字符串转换为布尔值，从而触发类型不匹配错误。

修复步骤 #

将这两个压缩级别配置从[runners.feature_flags]中移出，放到[[runners]]的直接子层级下（与executor、name等配置同级）。

修正后的config.toml示例 #

concurrent = 4
check_interval = 0

[session_server]
  session_timeout = 1800

[[runners]]
  name = "Docker executor runner"
  url = "..."
  id = 2963
  token = "...."
  token_obtained_at = 2023-02-23T12:11:19Z
  token_expires_at = 0001-01-01T00:00:00Z
  executor = "docker"
  ARTIFACT_COMPRESSION_LEVEL = "fast"
  CACHE_COMPRESSION_LEVEL = "fast"
  [runners.custom_build_dir]
  [runners.feature_flags]
    FF_NETWORK_PER_BUILD = true
    FF_USE_FASTZIP = true
  [runners.cache]
    MaxUploadedArchiveSize = 0
    [runners.cache.s3]
    [runners.cache.gcs]
    [runners.cache.azure]
  [runners.docker]
    tls_verify = false
    image = "ubuntu:20.04"
    privileged = false
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/cache"]
    shm_size = 0
    allowed_pull_policies = ["always", "if-not-present"]

补充说明 #

官方文档中提到的1或true作为布尔值合法，仅针对[runners.feature_flags]下的FF_开头特性开关，不适用于其他类型的配置项。确保不同类型的配置项放在对应的区块中，即可避免此类解析错误。
