Hello together,
DVLS 2026.3 added PostgreSQL as a database backend (release notes 2026.3.5.0, and the blog post "Run Devolutions Server on PostgreSQL" of Oct 14, 2026, which also mentions Linux and Docker deployments). The documentation has not been updated for the Docker image yet:
- "Advanced Docker configuration for Devolutions Server" still lists only SQL Server variables (DATABASE_HOST, DATABASE_PORT with default 1433, DATABASE_ENCRYPT, DATABASE_TRUST_SERVER_CERTIFICATE, AZURE_SQL_*) and describes the "SQL Server connection string".
- "Deploy Devolutions Server with Docker" lists an SQL Server instance as the only prerequisite.
- "Install Devolutions Server for Linux" still uses the SQL Server flow.
- "System requirements" only says "PostgreSQL is supported", without supported versions.
I inspected the image devolutions/devolutions-server:release-2026.3 (digest sha256:755c87a8...) without starting it:
- It ships Npgsql.dll and Npgsql.EntityFrameworkCore.PostgreSQL.dll.
- The entrypoint is the DVLS binary itself (--container-entrypoint), so there is no script that shows the variables.
- Devolutions.Server.dll contains a new variable DATABASE_TYPE and the error message "DATABASE_TYPE must be 'SqlServer', 'PostgreSQL', or 'SQLite'". It also contains DATABASE_PATH, DVLS_PG_DUMP_PATH, DVLS_PG_RESTORE_PATH and DVLS_DATABASE_UPGRADE_ON_STARTUP, plus an embedded PostgreSqlBaseline.sql.
My assumption is that the container is configured like this, but I have not confirmed it:
-e DATABASE_TYPE=PostgreSQL
-e DATABASE_HOST=<host> -e DATABASE_PORT=5432
-e DATABASE_NAME=<db> -e DATABASE_USERNAME=<user> -e DATABASE_PASSWORD=<password>
Questions:
1. Is DATABASE_TYPE=PostgreSQL officially supported with the Docker image? What are the exact accepted values (SqlServer / PostgreSQL / SQLite)?
2. How are DATABASE_ENCRYPT and DATABASE_TRUST_SERVER_CERTIFICATE mapped for PostgreSQL (SSL mode)? Are there PostgreSQL-specific variables?
3. Does the database have to exist before DVLS_INIT=true, or is it created automatically like on SQL Server?
4. DVLS_UPDATE_MODE creates a backup: does this need pg_dump / pg_restore (DVLS_PG_DUMP_PATH, DVLS_PG_RESTORE_PATH), and are these tools included in the image or do I have to provide them?
5. Which PostgreSQL versions are supported?
6. Is there an ETA for updating the Docker and Linux documentation?
Environment: Docker (current version) on a Linux x86_64 host, DVLS release-2026.3 (existing SQL Server instance on 2026.3.10.0, PostgreSQL planned only for a new test installation, no migration).
Thanks!
Best regards,
Alex
