How to Install Exalate for Jira Cloud on Docker

You can host Exalate for Jira Cloud on your own server. To do so, you need to install Exalate on Docker.

Steps to Install Exalate for Jira Cloud on Docker

1. Create directory and create docker-compose.yml file

Create a directory to hold the docker-compose file:

cd ~
mkdir exalate-jcloudnode

Create or download a docker-compose.yml file

Note: We recommend using the latest version of Exalate for Jira Cloud. It can be found in the Release History.

Enter the latest version in the image tag. For example, in image: idalko/jcloudnode:5.12.0, the version of Exalate for Jira Cloud is 5.12.0 .

The docker-compose.yml file should contain the following information in it:

version: '2' 
services:
  database:
    restart: unless-stopped
    image: postgres:12.19
    volumes:
      - ./persist/db:/var/lib/postgresql/data
      - ./createdb.sh:/docker-entrypoint-initdb.d/init-user-db.sh
    environment:
      # adapt the default passwords
      - DB_NAME=jcloudnode
      - DB_USER=idalko
      - DB_PASS=idalko
      - POSTGRES_PASSWORD=changeme
    networks:
      - database
 
  jcloudnode:
    restart: unless-stopped
 
    # use the latest version https://hub.docker.com/r/idalko/jcloudnode
    image: idalko/jcloudnode:5.12.0
    depends_on:
      - database #wait for postgres to be started, not for ready
    volumes:
      - ./persist/home:/opt/jcloudnode/data
    environment:
      # Add your environment settings here, check documentation for details
      - JCLOUDNODE_PG_HOST=database
      - JCLOUDNODE_PG_DB=exalate?gssEncMode=disable
      - JCLOUDNODE_PG_PWD=idalko
      - JCLOUDNODE_PG_USER=idalko
      - JCLOUDNODE_PORT=9002
 
       # When you deploy Exalate onto a server, you configure a DNS rule such that 
      #whenever people navigate to foo.com, they reach your server's Exalate. 
      #You set up SSL so that https://foo.com leads to your Exalate on your server.
      #Now you need to set environment variable NODE_SELF_URL=https://foo.com 
      #for your Exalate docker container.
 
      # Use following variables to link the node with nginx proxy
      # Replace francis-jcl.exalate.biz with the appropriate FQDN
      - LETSENCRYPT_HOST=francis-jcl.exalate.biz
      - VIRTUAL_HOST=francis-jcl.exalate.biz
      - VIRTUAL_PORT=9002
      - NODE_SELF_URL=https://foo.com
      # CACHE_EXPIRY_DURATION_HOURS variable defines how long the cache will remain in the app.
      # The default value of 8 hours can be changed by specifying the number of hours.
      - CACHE_EXPIRY_DURATION_HOURS=20
    
    networks:
      - database
      - proxy
 
 
networks:
  database:
    driver: bridge
  default:
    driver: bridge
  proxy:
    external:
        name: proxy

Connecting to Postgres 10 or Higher

For unencrypted connections from Exalate to a Postgres version 10 or higher, you need to disable gssEncMode with the following setting:

# exalate is the name of the database on the postgres instance
#
JCLOUDNODE_PG_DB=exalate?gssEncMode=disable

2. Ensure that a correct database is setup using a createdb.sh

Create or download a createdb.sh file (referenced from docker-compose.yml):

The file should contain the following information:

#!/bin/bash
  
TEST=`psql -U postgres <<-EOSQL
   SELECT 1 FROM pg_database WHERE datname='$DB_NAME';
EOSQL`
  
echo "******CREATING DOCKER DATABASE******"
if [[ $TEST == "1" ]]; then
    # database exists
    # $? is 0
    exit 0
else
psql -U postgres <<-EOSQL
   CREATE ROLE $DB_USER WITH LOGIN ENCRYPTED PASSWORD '${DB_PASS}' SUPERUSER;
EOSQL
  
psql -U postgres <<-EOSQL
   CREATE DATABASE $DB_NAME WITH OWNER $DB_USER ENCODING 'UNICODE' LC_COLLATE 'C' LC_CTYPE 'C' TEMPLATE template0;
EOSQL
  
psql -U postgres <<-EOSQL
   GRANT ALL PRIVILEGES ON DATABASE $DB_NAME TO $DB_USER;
EOSQL
fi
  
echo ""
echo "******DOCKER DATABASE CREATED******"

Ensure that the volumes are included in your backup strategy:

• persist

3. Set Environment Variables if necessary

Below, you can find the environment variables used for the app container. 

CACHE_EXPIRY_DURATION_HOURS	CACHE_EXPIRY_DURATION_HOURS=8	Defines how long the cache remains in the app. The default value of 8 hours can be changed by specifying the number of hours.
EXALATE_GROUP_CONSOLE_ADMIN	EXALATE_GROUP_CONSOLE_ADMIN=some_group_name	Grants access to the admin console to users added to this group.
JCLOUDNODE_PG_DB	JCLOUDNODE_PG_DB=exalate	Tells Exalate what is the Postgres database name for the Exalate application
JCLOUDNODE_PG_HOST	JCLOUDNODE_PG_HOST=database	Tells Exalate where is the Postgres database to connect is hosted
JCLOUDNODE_PG_PWD	JCLOUDENODE_PG_PWD=secret	Tells the Exalate application what is the Postgres database user's password for the Exalate application to perform queries with
JCLOUDNODE_PG_USER	JCLOUDNODE_PG_USER=exalate	Tells the Exalate application what is the Postgres database user name for the Exalate application to perform queries with
HTTP_HEADERS	HTTP_HEADERS="TestName1: testAddHeader1"	Allows additional information to pass between the clients and the server through the request header.
SMTP_FROM	SMTP_FROM=my.name@gmail.com	Email that is used to send error notifications
SMTP_HOST_NAME	SMTP_HOST_NAME=smtp.gmail.com	Host name of the SMTP server used to send error notifications
SMTP_LOGIN	SMTP_LOGIN=my.name	Login to the SMTP service
SMTP_PASS	SMTP_PASS=secret	Password to the SMTP service
SMTP_PORT	SMTP_PORT=587	Port (also check the TLS setting)
SMTP_TLS	SMTP_TLS=true	Can be set to false, but then the SMTP_PORT  should be set to the port, that accepts non-SSL and non-TLS connections
FEATURE_AI_ASSIST_ENABLED	FEATURE_AI_ASSIST_ENABLED=true	Switches on AI Assist feature in Exalate admin console. When enabled, users can use Exalate AI to generate sync rules. *The AI Assist feature requires a real-time internet connection.

Using a Proxy for Outgoing Connections

Whenever the Exalate node needs to use a proxy to establish outgoing connections, use the following parameters in the environment (naming should be obvious):

• PROXY_HTTP_HOST
• PROXY_HTTP_PORT
• PROXY_HTTPS_HOST
• PROXY_HTTPS_PORT

4. Start the Application

cd ~/exalate-jcloudnode
docker-compose up -d

5. Register the Node

To be able to fully use the functionality of your new node, it needs to be registered on the mapper.  This mapper acts as a DNS server, mapping tracker URLs to node URLs.

Please raise a ticket on the support portal providing the following:

• Jira Cloud instance URL
• URL of the Exalate node which has been deployed on-premise

How to Manage the Application on Docker

Run Queries to the Application's Database

You can find all tables using PSQLs \dt+ command:

\dt+

All the Postgres SQL queries are permitted

To exit the application's DB:

\q
# \q exits the psql 
exit
# exits the postgres user session
exit
# exits the exalatejcloudnode_database_1 bash session

Inspect the Application's Filesystem

cd ~/exalate-jcloudnode
docker exec -it exalatejcloudnode_jcloudnode_1 bash

Remove the Application

cd ~/exalate-jcloudnode
docker-compose rm

Remove the Application Data

cd ~/exalate-jcloudnode
# docker volume ls | grep exalatejcloudnode_vol |  awk '{ print $2 }' | xargs docker volume rm
docker volume rm exalatejcloudnode_voldatabase
docker volume rm exalatejcloudnode_voljcloudnode

System Administration Tasks

With the Exalate for Jira Cloud is running on your environment, you are also required to do the mandatory system administration tasks

• Backup (& restore tests)
• Disaster recovery procedure
• Upgrades whenever needed

Upgrading Exalate on Docker

If you need to upgrade Exalate on Docker, here are the steps to follow:

1. Edit the YAML File:

   Open the docker-compose.yml file in a text editor and modify the image tag for the service you wish to upgrade.

   # use the latest version https://hub.docker.com/r/idalko/jcloudnode
   image: idalko/jcloudnode:latest
   depends_on:
   - database #wait for postgres to be started, not for ready
   

   Replace latest with the latest or desired version tag.

2. Pull the Latest Image:

   From the directory containing your docker-compose.yml file, pull the latest image.

   docker-compose pull
   

3. Recreate the Container:

   Using Docker Compose, you can easily recreate the container with the new image.

   docker-compose up -d
   

   The -d flag runs the containers in detached mode. Docker Compose automatically stops the old container and starts a new one based on the updated image.

4. Post-Upgrade Checks:

   After starting the upgraded container, check to make sure everything is running as expected:

• Log into the Exalate interface and verify that all your configurations, connections are intact.
• Test out a few synchronizations to make sure they work as expected.
• Check for any errors in the Docker logs or the Exalate logs.
