* misc backend fixes:
- fix running w/o local minio
- ensure crawler image pull policy is configurable, loaded via chart value
- use digitalocean repo for main backend image (for now)
- add bucket_name to config only if using default bucket
* enable all behaviors, support 'access_endpoint_url' for default storages
* debugging: add 'no_delete_jobs' setting for k8s and docker to disable deletion of completed jobs
- collections defined by name per archive
- can update collections with additional metadata (currently just description)
- crawl config api accepts a list of collections by name, resolved to collection uids and stored in config
- finished crawls also associated with collection list
- /archives/{aid}/collections/{name} can list all crawl artifacts (wacz files) from a named collection (in frictionless data package-ish format)
- /archives/{aid}/collections/$all lists all crawled artifacts for the archive
readiness check: add /healthz endpoints for app and nginx
ingress: add /data/ route to local bucket
storage improvements:
- for default storages, store path only, and prepend default storage access endpoint
- collections api returns the paths using the storage access endpoint
- define default storages as secrets in k8s (can support multiple), hard-coded in docker (only one for now)
- 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
- supported in both docker and k8s
- additional pods with same job id automatically use same crawl state in redis
- support dynamic scaling (#2) via /scale endpoint - k8s job parallelism adjusted dynamically for running job (only supported in k8s so far)
- run as child process using aioprocessing
- cleanup: support cleanup of orphaned containers
- timeout: support crawlTimeout via check in cleanup loop
- support crawl listing + crawl stopping
- support for creating, deleting crawlconfigs, running crawls on-demand
- config stored in volume
- list to docker events and clean up containers when they exit
- 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)
