Fixes#1893
- Removes crawl workflow-scoped configmaps, and replaces with operator-controlled
per-crawl configmaps that only contain the json config passed to Browsertrix
Crawler (as a volume).
- Other configmap settings replaced are replaced the custom CrawlJob options
(mostly already were, just added profile_filename and storage_filename)
- Cron jobs also updated to create CrawlJob without relying on configmaps,
querying the db for additional settings.
- The `userid` associated with cron jobs is set to the user that last modified
the schedule of the crawl, rather than whomever last modified the workflow
- Various functions that deal with updating configmaps have been removed,
including in migrations.
- New migration 0029 added to remove all crawl workflow configmaps
- add a 'expire_at_duration_seconds' which is 75% of actual presign
duration time, or <25% remaining until presigned URL actually expires to
ensure presigned URLs are updated early than when they actually expire
- set cached expireAt time to the renew at time for more frequent
updates
- update QA configmap in place with updated presigned URLs when expireAt
time is reached
- mount qa config volume under /tmp/qa/ without subPath to get automatic
updates, which crawler will handle
- tests: fix qa test typo (from main)
- fixes#1864
Currently, the workflow crawl settings were not being included at all in
QA runs.
This mounts the crawl workflow config, as well as QA configmap, into QA
run crawls, allowing for page limits from crawl workflow to be applied
to QA runs.
It also allows a different number of browser instances to be used for QA
runs, as QA runs might work better with less browsers, (eg. 2 instead of
4). This can be set with `qa_browser_instances` in helm chart.
Default qa browser workers to 1 if unset (for now, for best results)
Fixes#1828
- ensure max_crawler_memory_size is inited before it is set!
- pass profile_browser_memory / profile_browser_cpu from chart values
- map volume to /tmp/home to avoid persisting /tmp for profiles
- 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

Supports running QA Runs via the QA API!
Builds on top of the `issue-1498-crawl-qa-backend-support` branch, fixes
#1498
Also requires the latest Browsertrix Crawler 1.1.0+ (from
webrecorder/browsertrix-crawler#469 branch)
Notable changes:
- QARun objects contain info about QA runs, which are crawls
performed on data loaded from existing crawls.
- Various crawl db operations can be performed on either the crawl or
`qa.` object, and core crawl fields have been moved to CoreCrawlable.
- While running,`QARun` data stored in a single `qa` object, while
finished qa runs are added to `qaFinished` dictionary on the Crawl. The
QA list API returns data from the finished list, sorted by most recent
first.
- Includes additional type fixes / type safety, especially around
BaseCrawl / Crawl / UploadedCrawl functionality, also creating specific
get_upload(), get_basecrawl(), get_crawl() getters for internal use and
get_crawl_out() for API
- Support filtering and sorting pages via `qaFilterBy` (screenshotMatch, textMatch)
along with `gt`, `lt`, `gte`, `lte` params to return pages based on QA results.

- Backend: Use separate resource constraints for profiles: default
profile browser resources to either 'profile_browser_cpu' /
'profile_browser_memory' or single browser 'crawler_memory_base' /
'crawler_cpu_base', instead of scaled to the number of browser workers
- Frontend: check that profile html page is loading, keep retrying if
still getting nginx error instead of loading an iframe with the error.
Fixes#1598 (Copy of #1599 from 1.9.4)
Supports setting WARC prefix for WARCs inside WACZ to `<org slug>-<slug
[crawl name | first seed host]>`.
- Prefix set via WARC_PREFIX env var, supported in browsertrix-crawler
1.0.0-beta.4 or higher
If crawl name is provided, uses crawl name, other hostname of first
seed. The name is 'sluggified', using lowercase alphanum characters
separated by dashes.
Ex: in an organization called `Default Org`, a crawl of
`https://specs.webrecorder.net/` and no name will have WARCs named:
`default-org-specs-webrecorder-net-....warc.gz`
If the crawl is given the name `SPECS`, the WARCs will be named
`default-org-specs-manual-....warc.gz`
Fixes#412 in a default way.
Fixes#1385
## Changes
Supports multiple crawler 'channels' which can be configured to
different browsertrix-crawler versions
- Replaces `crawler_image` in helm chart with `crawler_channels` array
similar to how storages are handled
- The `default` crawler channel must always be provided and specifies
the default crawler image
- Adds backend `/orgs/{oid}/crawlconfigs/crawler-channels` API endpoint
to fetch information about available crawler versions (name, image, and
label) and test
- Adds crawler channel select to workflow creation/edit screens and
profile creation dialog, and updates related API endpoints and
configmaps accordingly. The select dropdown is shown only if more than
one channel is configured.
- Adds `crawlerChannel` to workflow and crawl details.
- Add `image` to crawler image, used to display actual image used as
part of the crawl.
- Modifies `crawler_crawl_id` backend test fixture to use `test` crawler
version to ensure crawler versions other than latest work
- Adds migration to add `crawlerChannel` set to `default` to existing
workflow and profile objects and workflow configmaps

Previously, the crawler pods use preferred node affinity, instead of
required node affinity. This results in crawler nodes running on the
main node pool. Instead, we want to ensure crawler nodes are running on
dedicated node pool (if configured).
- Converts 'preferred node affinity' to 'required node affinity' for
the node pool, while keeping preferred pod affinity for keeping all
crawler / redis pods together.
- For profiles, updates to same node affinity, and also adds
resource constraint to match a single crawler for profile browser,
which did not have resource constraints.
Fixes#1364
Regression fix for issue introduced in storage refactoring (see issue
for more details).
Changes:
1. Add `profiles/` prefix to profile filename passed in to crawler for
profile creation and written into db
2. Remove hardcoded `profiles/` prefix from crawler YAML
3. Add migration to add `profiles/` prefix to profile filenames that
don't already have it, including updating PROFILE_FILENAME in ConfigMaps
This way between the related storage document and the profile filename,
we have the full path to the object in the database rather than relying
on additional prefixes hardcoded into k8s job YAML files.
Note that this as a follow-up it'll be necessary to manually move any
profiles that had been written into the `<oid>` "directory" in object
storage rather than `<oid>/profiles` to the latter. This should only
affect profiles created very recently in a 1.8.0-beta release.
- move authsign secret to signer and make port configurable
- rename storages to more general ops-configs
- put 'storages.json' path into env var
- rename backend secret to backend-auth
- cronjobs: don't keep succeeded jobs around, triggers operator update
Fixes#1337
Crawl timeout is tracked via `elapsedCrawlTime` field on the crawl
status, which is similar to regular crawl execution time, but only
counts one pod if scale > 1. If scale == 1, this time is equivalent.
Crawl is gracefully stopped when the elapsed execution time exceeds the
timeout. For more responsiveness, also adding current crawl time since
last update interval.
Details:
- handle crawl timeout via elapsed crawl time - longest running time of a
single pod, instead of expire time.
- include current running from last update for best precision
- more accurately count elapsed time crawl is actually running
- store elapsedCrawlTime in addition to crawlExecTime, storing the
longest duration of each pod since last test interval

Instead of adding the app templates launched from the backend via
`backend/btrixcloud/templates`, add them to a configmap and mount the
configmap in the same location.
This allows these templates to be updated, like other values in
charts/... without having to rebuild any of the images, speeding up dev
and maintenance time.
Changes include:
- move backend/btrixcloud/templates -> chart/app-templates/
- add app-templates/*.yaml to app-templates configmap
- mount app-templates configmap to /app/btrixcloud/templates/ in api and op containers
