Docker implementation of Greenbone Vulnerability Management (GVM) / OpenVAS
https://github.com/isaudits/docker-gvm
The easiest way to run is using docker-compose. An example compose file can be found in the github repo at https://github.com/isaudits/docker-gvm/blob/master/docker-compose.yml.
The sample compose file references an .env file for defining environment variables at config/local.env; a sample .env file can also be found in the github repo.
The following environment variables can be defined in your docker-compose file or the referenced .env file, or can be passed into docker command line:
- UPDATE_ON_START - run feed update script on launch
- PUID - PID of non-root user (1000)
- PGID - GID of non-root user (100)
- TZ - Time Zone (America/New_York)
- GVM_USER - username of default GVM user (admin)
- GVM_PASSWORD - password for default GVM user (admin - can be changed in GSA later)
- GVMD_MAX_IPS_PER_TARGET - Max hosts per scan target (4096)
- GSA_TIMEOUT - HTTP timeout for GSA (600)
- SMTP_HOST - SMTP relay for emailing reports
- SMTP_PORT - SMTP relay port
- SMTP_MASQ - SMTP masquerade domain
When launching a new build that requires a DB schema migration, the migration will fail while there are any plugin updates being processed. This will likely occur if your instance is configured to download plugin updates on startup.
If you see error messages in the console such as "SCAP sync already running" followed by "gvmd: cannot migrate SCAP database" then an ongoing sync is preventing the initial migration from taking place. GVMD will fail to launch until this process is completed, so just allow the process to complete and GVMD should eventually start.
Major updates to schema could require some database tables to be reinitialized. GVMD will do this upon start, however GSA will not load until this process completes and the GVMD daemon is started.
TLDR; upon first launch, just walk away for a bit and have a coffee!
No known upgrade issues from 20.8.1 build or higher. Previous build notes apply to upgrades from previous builds. Going forward, release build tags will only be updated to a new tag if minor release causes upgrade or dependency issues as was the case from 20.8 to 20.8.1. Major releases (e.g. 21.4 vs 20.8 will continue to receive new build tags).
Upgraded base image from 20.8 release to Ubuntu 20.04 (Focal) due to required dependency versions not being upgraded in 18.04 (Bionic). This also results in an upgrade of Postgres from 10 to 12, which will require the GVM database to either be manually updated or recreated.
At this point, we have not found a simple way to perform an in-place upgrade of the database. You can TRY the following steps at your own risk (this is unsupported and we will not accept any blame if you brick a production database nor will we respond to any support requests for assistance with upgrading a database).
# backup existing volume
docker volume rm gvm_db_bak
docker volume create gvm_db_bak
docker run --rm -it -v gvm_db:/from -v gvm_db_bak:/to alpine ash -c "cd /from ; cp -av . /to"
# export data to temp volume
docker volume rm gvm_db_temp
docker volume create gvm_db_temp
# use 20.8 image to export database
docker run --rm -it -v gvm_db:/var/lib/postgresql/data -v gvm_db_temp:/backup --entrypoint /bin/bash isaudits/gvm:gvm-20.8
# dump gvm database
s6-setuidgid postgres /usr/lib/postgresql/10/bin/postgres &
sudo -u abc pg_dump -O gvmd >/backup/gvmd_dump.sql
exit
# use 20.8.1 image to restore database
docker volume rm gvm_db
docker volume create gvm_db
docker run --rm -it -v gvm_db:/var/lib/postgresql/data -v gvm_db_temp:/backup --entrypoint /bin/bash isaudits/gvm:gvm-20.8.1
# initialize GVMD database and restore backup
cat /etc/cont-init.d/50-postgres | /bin/bash
s6-setuidgid postgres /usr/lib/postgresql/12/bin/postgres &
sudo -u abc psql -f /backup/gvmd_dump.sql gvmd
exit
# undo if something screws up
docker volume rm gvm_db
docker volume create gvm_db
docker run --rm -it -v gvm_db_bak:/from -v gvm_db:/to alpine ash -c "cd /from ; cp -av . /to"
# if all looks ok, delete temp volumes
docker volume rm gvm_db_temp
docker volume rm gvm_db_bak
When upgrading from GVM 11, the system has to migrate default reports from those included with source of GVM 11 (/usr/local/share/gvm/gvmd/report_formats/) to the new feed based reports. This process fails if the directory is empty (which is the case when this directory lives inside a docker image for version 11). Solution was to populate this directory inside the image from our GVM11 base image
Default path for ospd socket has changed from /tmp/ospd.sock to /var/run/ospd/ospd.sock; This path has to be changed in the ospd.conf file. Solution was to implement commands on startup to set default values in ospd.conf
Have to manually change scanner pid path on existing scanner if upgraded from GVM 11; on portainer, use command shell as user abc:
gvmd --get-scanners
gvmd --modify-scanner=<UUID> --scanner-host=/var/run/ospd/ospd.sock
