Gitlab 轻量化运行

Gitlab 确实不错,但也确实吃内存和 CPU。这篇文章其实是从两篇文章里面抄来的。

首先是这篇,好像是一个对 Git 颇有研究的同学写的。我先照着直接做了,CPU 从 20% 直降到 3%,内存占用从 4G 降到 2G。

# 关闭电子邮件相关功能
gitlab_rails['smtp_enable'] = false
gitlab_rails['gitlab_email_enabled'] = false
gitlab_rails['incoming_email_enabled'] = false

# Terraform
gitlab_rails['terraform_state_enabled'] = false

# Usage Statistics
gitlab_rails['usage_ping_enabled'] = false
gitlab_rails['sentry_enabled'] = false
grafana['reporting_enabled'] = false

# 关闭容器仓库功能
gitlab_rails['gitlab_default_projects_features_container_registry'] = false
gitlab_rails['registry_enabled'] = false
registry['enable'] = false
registry_nginx['enable'] = false

# 包仓库
gitlab_rails['packages_enabled'] = false
gitlab_rails['dependency_proxy_enabled'] = false

# GitLab KAS
gitlab_kas['enable'] = false
gitlab_rails['gitlab_kas_enabled'] = false

# Mattermost
mattermost['enable'] = false
mattermost_nginx['enable'] = false

# Kerberos
gitlab_rails['kerberos_enabled'] = false
sentinel['enable'] = false

# GitLab Pages
gitlab_pages['enable'] = false
pages_nginx['enable'] = false

# 禁用 PUMA 集群模式
puma['worker_processes'] = 0
puma['min_threads'] = 1
puma['max_threads'] = 2

# 降低后台守护进程并发数
sidekiq['max_concurrency'] = 5

gitlab_ci['gitlab_ci_all_broken_builds'] = false
gitlab_ci['gitlab_ci_add_pusher'] = false

# 关闭监控
prometheus_monitoring['enable'] = false
alertmanager['enable'] = false
node_exporter['enable'] = false
redis_exporter['enable'] = false
postgres_exporter['enable'] = false
pgbouncer_exporter['enable'] = false
gitlab_exporter['enable'] = false
grafana['enable'] = false
sidekiq['metrics_enabled'] = false

然后是官方教程

puma['worker_processes'] = 0

sidekiq['max_concurrency'] = 10

prometheus_monitoring['enable'] = false

gitlab_rails['env'] = {
  'MALLOC_CONF' => 'dirty_decay_ms:1000,muzzy_decay_ms:1000'
}

gitaly['cgroups_count'] = 2
gitaly['cgroups_mountpoint'] = '/sys/fs/cgroup'
gitaly['cgroups_hierarchy_root'] = 'gitaly'
gitaly['cgroups_memory_enabled'] = true
gitaly['cgroups_memory_limit'] = 250000
gitaly['cgroups_cpu_enabled'] = true
gitaly['cgroups_cpu_shares'] = 512

gitaly['concurrency'] = [
  {
    'rpc' => "/gitaly.SmartHTTPService/PostReceivePack",
    'max_per_repo' => 3
  }, {
    'rpc' => "/gitaly.SSHService/SSHUploadPack",
    'max_per_repo' => 3
  }
]
gitaly['env'] = {
  'LD_PRELOAD' => '/opt/gitlab/embedded/lib/libjemalloc.so',
  'MALLOC_CONF' => 'dirty_decay_ms:1000,muzzy_decay_ms:1000',
  'GITALY_COMMAND_SPAWN_MAX_PARALLEL' => '2'
}

哦对了,上面所有东西都写到 /etc/gitlab/gitlab.rb 里面,而不要写到 docker-compose.yaml 里面。


后记:按照官方文档操作,gitali 一直在重启,完全没办法用。放弃吧……
