JIRA Docker Configuration

Getting Started

These instructions assume that Docker is already installed and running on the machine in question.

Clone the JIRA Docker Configuration to the machine:

$ git clone [email protected]:jeevb/jira-docker.git

Edit the following environment variables in .env using your favorite editor:

POSTGRES_DB=jiradb
POSTGRES_USER=postgres
POSTGRES_PASSWORD=postgres

Add SSL certificates to nginx/ssl/. This should be easy as moving them to this folder. For testing purposes, generating self-signed certificates would suffice:

$ openssl req -x509 -nodes -days 365 -newkey rsa:2048 -sha256 -keyout jira-docker/nginx/ssl/jira.key -out jira-docker/nginx/ssl/jira.crt

NOTE: Do not use self-signed certificates in production.

Generate a strong DHE parameter:

$ openssl dhparam -out jira-docker/nginx/ssl/dhparam.pem 4096

Build and run the containers in detached mode using docker-compose:

$ cd jira-docker
$ docker-compose up -d

Navigate to the JIRA instance at https://jira.example.com on your favorite browser to start setting up.

Setting up the database

Choose the option to use a PostgreSQL database, and set the host to postgres. Leave the port unchanged. All other options will be as specified in the .env file.

Increase Available Memory

To keep JIRA as snappy as it can possibly be, it should be run with at least 2 cores and 4GB ram. t2.medium on AWS EC2 would be a good candidate for such a configuration. With more ram, more heap space can be allocated to the Java Virtual Machine (JVM) on which JIRA will be run. To do so,

Run the admin container using docker-compose:

$ docker-compose run --rm admin

Open up the required configuration file:

$ vim /opt/atlassian/jira/bin/setenv.sh

Edit the JVM_MINIMUM_MEMORY and JVM_MAXIMUM_MEMORY lines to look as follows:

JVM_MINIMUM_MEMORY="1024m"
JVM_MAXIMUM_MEMORY="2048m"

Restart the containers:

$ docker-compose restart

Mismatched URL Scheme

Since Nginx will be used as a reverse proxy server in front of JIRA, the following change will have to be made:

Run the admin container using docker-compose:

$ docker-compose run --rm admin

Open up JIRA server configuration file:

$ vim /opt/atlassian/jira/conf/server.xml

Add the following lines to the file within the Connector node:

...
    <Service name="Catalina">

        <Connector port="8080"

                   maxThreads="150"
                   minSpareThreads="25"
                   connectionTimeout="20000"

                   enableLookups="false"
                   maxHttpHeaderSize="8192"
                   protocol="HTTP/1.1"
                   useBodyEncodingForURI="true"
                   redirectPort="8443"
                   acceptCount="100"
                   disableUploadTimeout="true"
<!-- Lines added to solve the URL scheme mismatch -->
                   scheme="https"
                   proxyName="jira.example.com"
                   proxyPort="443"/>
...

Restart the containers:

$ docker-compose restart
