bonitasoft/bonita-postgres Docker 镜像 - 轩辕镜像

Pre-configured Postgres database image to work with Bonita

This image is based on the official Postgres image.

Additions

Configuration

The property max_prepared_transactions is required by Bonita and is set to 100.

Databases

This image is configured with the two databases required by Bonita:

• bonita (connection user bonita, password bpm)
• business_data (connection user business_data, password bpm)

How to use this image

• Default way:

shell
docker run -d --name bonita-postgres -p 5432:5432 bonitasoft/bonita-postgres:15.3

• Recommended way, to have datafiles out of container by binding a volume to /var/lib/postgresql/data:

shell
docker run -d \
      --name bonita-postgres \
      -p 5432:5432 \
      -v /my/postgres/datadir:/var/lib/postgresql/data \
      bonitasoft/bonita-postgres:15.3

• With local volume for backup/restore and script exchange:

shell
docker run -d \
      --name bonita-postgres \
      -p 5432:5432 \
      -v /my/postgres/datadir:/var/lib/postgresql/data \
      -v /my/sql/folder:/opt/bonita/sql \
      bonitasoft/bonita-postgres:15.3

Container shell access

shell
docker exec -it bonita-postgres bash

Viewing Postgres logs

shell
docker logs bonita-postgres

How to restore dump

It will restore dumps present in the volume /opt/bonita/dump

For plain text sql form, dumps must be named bonita.dump and business_data.dump

Create those dump using:

shell
pg_dump -h localhost -p 5432 -Ubonita bonita > /opt/bonita/dump/bonita.dump
pg_dump -h localhost -p 5432 -Ubusiness_data business_data > /opt/bonita/dump/business_data.dump

For compressed format, dumps must be named bonita.pgdump and business_data.pgdump. This format is used with a .list file that allow to whitelist items to restore:

shell
# --quote-all-identifiers : ensure no issues with bonita columns name that use a PostgreSQL reserved word
# --encoding=utf8 : required
# -F c : use PostgreSQL compress format
pg_dump -h localhost -p 5432 -U bonita --quote-all-identifiers --encoding=utf8 -F c bonita > /opt/bonita/dump/bonita.pgdump

# prepare white-list file for pg_restore
# this will read backup file and generate a TOC (Table Of Content) stored in a white list file
# then edit this file to comment with a `;` items you don't want to restore 
pg_restore -l /opt/bonita/dump/bonita.pgdump > /opt/bonita/dump/bonita.list 

# same for BDM
pg_dump -h localhost -p 5432 -U business_data --quote-all-identifiers --encoding=utf8 -F c business_data > /opt/bonita/dump/business_data.pgdump
pg_restore -l /opt/bonita/dump/business_data.pgdump > /opt/bonita/dump/business_data.list 

Then run the docker using volume -v /my/postgres/dump:/opt/bonita/dump

Note: if container already exists, it must be removed, using `docker rm <CONTAINER_ID>`, unless restore will not be applied

Restore dump from file not using default 'bonita' schema

• Create a container with:
  • Extra parameter -e POSTGRES_PASSWORD=mysecretpassword, in order to be able to access the tables with a known user (postgres) and password
  • Extra volume mapping parameter with the dump file, to access it easily from within the container. For example:

    shell
    docker run -d --name postgres-from-dump -p 5432:5432 -e POSTGRES_PASSWORD=mysecretpassword -v /my/postgres/dump:/opt/bonita/dump bonitasoft/bonita-postgres:15.3
    

• Access the new container through docker exec -it postgres-from-dump
• Run psql -U postgres bonita < ./my_dump_file.sql
