* helm chart tweaks:
- lower mem requirements for backend and crawler
- disable cors in ingress to pass through cors headers from backend
- crawler statefulset: use ordered instead of parallel scaling policy to avoid single crawl taking up all crawling capacity quickly
* resource constraints: (fixes#895)
- for cpu, only set cpu requests
- for memory, set mem requests == mem limits
- add missing resource constraints for minio and scheduled job
- for crawler, set mem and cpu constraints per browser, scale based on browser instances per crawler
- add comments in values.yaml for crawler values being multiplied
- default values: bump crawler to 650 millicpu per browser instance just in case
cleanup: remove unused entries from main backend configmap
Operator: Modified init behavior to only load redis when at least one crawler pod available:
- waits for at least one crawler pod to be available before starting redis pod, to avoid situation where many crawler pods are in pending mode, but redis pods are still running.
- redis statefulset starts at scale of 0
- once crawler pod becomes available, redis sts is scaled to 1 (via `initRedis==true` status)
- crawl remains in 'starting' or 'waiting_capacity' state until pod becomes available without redis pod running
- set to 'running' state only after redis and at least one crawler pod is available
- if no crawler pods available after running, or, if stuck in starting for >60 seconds, switch to 'waiting_capacity' state
- when switching to 'waiting_capacity', also scale down redis to 0, wait for crawler pod to become available, only then scale up redis to 1, and get back to 'running'
other tweaks:
- add new status field 'initRedis', default to false, not displayed
- crawler pod: consider 'ContainerCreating' state as available, as container will not be blocked by resource limits
- add a resync after 3 seconds when waiting for crawler pod or redis pod to become available, configurable via 'operator_fast_resync_secs'
- set_state: if not updating state, ensure state reflects actual value in db
concurrent crawl limits: (addresses #866)
- support limits on concurrent crawls that can be run within a single org
- change 'waiting' state to 'waiting_org_limit' for concurrent crawl limit and 'waiting_capacity' for capacity-based
limits
orgs:
- add 'maxConcurrentCrawl' to new 'quotas' object on orgs
- add /quotas endpoint for updating quotas object
operator:
- add all crawljobs as related, appear to be returned in creation order
- operator: if concurrent crawl limit set, ensures current job is in the first N set of crawljobs (as provided via 'related' list of crawljob objects) before it can proceed to 'starting', otherwise set to 'waiting_org_limit'
- api: add org /quotas endpoint for configuring quotas
- remove 'new' state, always start with 'starting'
- crawljob: add 'oid' to crawljob spec and label for easier querying
- more stringent state transitions: add allowed_from to set_state()
- ensure state transitions only happened from allowed states, while failed/canceled can happen from any state
- ensure finished and state synched from db if transition not allowed
- add crawl indices by oid and cid
frontend:
- show different waiting states on frontend: 'Waiting (Crawl Limit) and 'Waiting (At Capacity)'
- add gear icon on orgs admin page
- and initial popup for setting org quotas, showing all properties from org 'quotas' object
tests:
- add concurrent crawl limit nightly tests
- fix state waiting -> waiting_capacity
- ci: add logging of operator output on test failure
* crawlconfig: fix default filename template, make configurable
- make default crawl file template configurable with 'default_crawl_filename_template' value in values.yaml
- set to '@ts-@hostsuffix.wacz' by default
- allow updating via 'crawlFilenameTemplate' in crawlconfig patch, which updates configmap
- tests: add test for custom 'default_crawl_filename_template'
* Btrixjobs Operator - Phase 1 (#679)
- add metacontroller and custom crds
- add main_op entrypoint for operator
* Btrix Operator Crawl Management (#767)
* operator backend:
- run operator api in separate container but in same pod, with WEB_CONCURRENCY=1
- operator creates statefulsets and services for CrawlJob and ProfileJob
- operator: use service hook endpoint, set port in values.yaml
* crawls working with CrawlJob
- jobs start with 'crawljob-' prefix
- update status to reflect current crawl state
- set sync time to 10 seconds by default, overridable with 'operator_resync_seconds'
- mark crawl as running, failed, complete when finished
- store finished status when crawl is complete
- support updating scale, forcing rollover, stop via patching CrawlJob
- support cancel via deletion
- requires hack to content-length for patching custom resources
- auto-delete of CrawlJob via 'ttlSecondsAfterFinished'
- also delete pvcs until autodelete supported via statefulset (k8s >1.27)
- ensure filesAdded always set correctly, keep counter in redis, add to status display
- optimization: attempt to reduce automerging, by reusing volumeClaimTemplates from existing children, as these may have additional props added
- add add_crawl_errors_to_db() for storing crawl errors from redis '<crawl>:e' key to mongodb when crawl is finished/failed/canceled
- add .status.size to display human-readable crawl size, if available (from webrecorder/browsertrix-crawler#291)
- support new page size, >0.9.0 and old page size key (changed in webrecorder/browsertrix-crawler#284)
* support for scheduled jobs!
- add main_scheduled_job entrypoint to run scheduled jobs
- add crawl_cron_job.yaml template for declaring CronJob
- CronJobs moved to default namespace
* operator manages ProfileJobs:
- jobs start with 'profilejob-'
- update expiry time by updating ProfileJob object 'expireTime' while profile is active
* refactor/cleanup:
- remove k8s package
- merge k8sman and basecrawlmanager into crawlmanager
- move templates, k8sapi, utils into root package
- delete all *_job.py files
- remove dt_now, ts_now from crawls, now in utils
- all db operations happen in crawl/crawlconfig/org files
- move shared crawl/crawlconfig/org functions that use the db to be importable directly,
including get_crawl_config, add_new_crawl, inc_crawl_stats
* role binding: more secure setup, don't allow crawler namespace any k8s permissions
- move cronjobs to be created in default namespace
- grant default namespace access to create cronjobs in default namespace
- remove role binding from crawler namespace
* additional tweaks to templates:
- templates: split crawler and redis statefulset into separate yaml file (in case need to load one or other separately)
* stats / redis optimization:
- don't update stats in mongodb on every operator sync, only when crawl is finished
- for api access, read stats directly from redis to get up-to-date stats
- move get_page_stats() to utils, add get_redis_url() to k8sapi to unify access
* Add migration for operator changes
- Update configmap for crawl configs with scale > 1 or
crawlTimeout > 0 and schedule exists to recreate CronJobs
- add option to rerun last migration, enabled via env var and by running helm with --set=rerun_last_migration=1
* subcharts: move crawljob and profilejob crds to separate subchart, as this seems best way to guarantee proper install order with + update on upgrade with helm, add built btrix-crds-0.1.0.tgz subchart
- metacontroller: use release from ghcr, add metacontroller-helm-v4.10.1.tgz subchart
* backend api fixes
- ensure changing scale of crawl also updates it in the db
- crawlconfigs: add 'currCrawlSize' and 'lastCrawlSize' to crawlconfig api
