Fixes#2673
Changes in this PR:
- Adds a new `file_uploads.py` module and corresponding `/files` API
prefix with methods/endpoints for uploading, GETing, and deleting seed
files (can be extended to other types of files moving forward)
- Seed files are supported via `CrawlConfig.config.seedFileId` on POST
and PATCH endpoints. This seedFileId is replaced by a presigned url when
passed to the crawler by the operator
- Seed files are read when first uploaded to calculate `firstSeed` and
`seedCount` and store them in the database, and this is copied into the
workflow and crawl documents when they are created.
- Logic is added to store `firstSeed` and `seedCount` for other
workflows as well, and a migration added to backfill data, to maintain
consistency and fix some of the pymongo aggregations that previously
assumed all workflows would have at least one `Seed` object in
`CrawlConfig.seeds`
- Seed file and thumbnail storage stats are added to org stats
- Seed file and thumbnail uploads first check that the org's storage
quota has not been exceeded and return a 400 if so
- A cron background job (run weekly each Sunday at midnight by default,
but configurable) is added to look for seed files at least x minutes old
(1440 minutes, or 1 day, by default, but configurable) that are not in
use in any workflows, and to delete them when they are found. The
backend pods will ensure this k8s batch job exists when starting up and
create it if it does not already exist. A database entry for each run of
the job is created in the operator on job completion so that it'll
appear in the `/jobs` API endpoints, but retrying of this type of
regularly scheduled background job is not supported as we don't want to
accidentally create multiple competing scheduled jobs.
- Adds a `min_seed_file_crawler_image` value to the Helm chart that is
checked before creating a crawl from a workflow if set. If a workflow
cannot be run, return the detail of the exception in
`CrawlConfigAddedResponse.errorDetail` so that we can display the reason
in the frontend
- Add SeedFile model from base UserFile (former ImageFIle), ensure all APIs
returning uploaded files return an absolute pre-signed URL (either with external origin or internal service origin)

- set memory limit to 1.2x memory request to provide extra padding and
avoid OOM
- attempt to resize crawler pods by 1.2x when exceeding 90% of available
memory
- do a 'soft OOM' (send extra SIGTERM) to pod when reaching 100% of
requested memory, resulting in faster graceful restart, but avoiding a
system-instant OOM Kill
- Fixes#1632

* keep track of per pod status on crawljob:
- crashes time, and reason
- 'used' vs 'allocated' resources
- 'percent' used / allocated
* crawl log errors: log error when crawler crashes via OOM, either via redis error log
or to console
* add initial autoscaling support!
- detect if metrics server is available via K8SApi.is_pod_metrics_available()
- if available, use metrics for 'used' fields
- if no metrics, set memory used for redis only (using redis apis)
- allow overriding memory and cpu via newMemory and newCpu settings on pod status
- scale memory / cpu based on newMemory and newCpu setting
- templates: update jinja templates to allow restarting crawler and redis with new resources
- ci: enable metrics-server on k3d, microk8s and nightly k3d ci runs
* roles: cleanup unused roles, add permissions for listing metrics
* stats for running crawls:
- update in db via operator
- avoids losing stats if redis pod happens to be done
- tradeoff is more db access in operator, but less extra connections to redis + already
loading from db in backend
- size stat: ensure size of previous files is added to the stats
* crawler deployment tweaks:
- adjust cpu/mem per browser
- add --headless flag to configmap to use new headless mode by default!
* 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

- use statefulsets instead of deployments for mongo, redis, signer
- use k8s job + statefulset for running crawls
- use separate statefulset for crawl (scaled) and single-replica redis stateful set
- move crawl job update login to crawl_updater
- remove shared redis chart
package refactor:
- move to shared code to 'btrixcloud'
- move k8s to 'btrixcloud.k8s'
- move docker to 'btrixcloud.docker'
* backend: k8s:
- support crawls with multiple wacz files, don't assume crawl complete after first wacz uploaded
- if crawl is running and has wacz file, still show as running
- k8s: allow configuring node selector for main pods (eg. nodeType=main) and for crawlers (eg. nodeType=crawling)
- profiles: support uploading to alternate storage specified via 'shared_profile_storage' value is set
- misc fixes for profiles
* backend: ensure docker run_profile api matches k8s
k8s chart: don't delete pvc and pv in helm chart
* dependency: bump authsign to 0.4.0
docker: disable public redis port
* profiles: fix path, profile browser return value
* fix typo in presigned url cacheing
- add liveness probe for crawls, configurable via 'crawler_liveness_port'
- add User system:anonymous permissions
- treat jobs that have exceeded total as 'partial_complete' (experimental)
- Add default vs custom (s3) storage
- K8S: All storages correspond to secrets
- K8S: Default storages inited via helm
- K8S: Custom storage results in custom secret (per archive)
- K8S: Don't add secret per crawl config
- API for changing storage per archive
- Docker: default storage just hard-coded from env vars (only one for now)
- Validate custom storage via aiobotocore before confirming
- Data Model: remove usage from users
- Data Model: support adding multiple files per crawl for parallel crawls
- Data Model: track completions for parallel crawls
- Data Model: initial support for tags per crawl, add collection as 'coll' tag
README fixes
- replace storages with archives, which have a single storage (for now)
- crawls associated with archives
- users below to archive, with one admin user (if archive created by default)
- update crawlconfig for latest browsertrix-crawler (0.4.4)
- k8s: fix permissions for crawler role
- k8s: fix minio service (now requiring two ports)
- working apis for adding crawls, removing crawls in mongo, mapped to k8s cronjobs
- more complete crawl spec
- option to start on-demand job from cronjobs
- optional minio in separate deployment/service
