## Description
This package contains example docker file and supporting scripts to run Informatica CLoud Secure Agent on a Docker Container
## Use
This package contains example docker file and supporting scripts to run Informatica CLoud Secure Agent on a Docker Container.
Note that this is not an official or supported method how to run Informatica Secure Agent. It is useful though to leearning how to setup secure agent, create agent clusters or test integrations
Full containerization of Secure agent is non trivial as it requires custom configuration of agent if deem to use this method as your runtime
## 1. Prepare Org for Agent installation
### 1.1 Create User
1. Create IICS Native user account which will be used to connect secure agent and assign user to Admin Group
Follow naming convention that includes company domain and environment such as `sa_login@acme.com.dev`
2. Login to informatica Cloud to activate the user and retrive the Secure Agent Token on the Administration/Runtime Environments page
![Secure Token](../images/IC_SA_Token.png)
## 2. Build a Docker Image
1. Make sure you have docker installed, go to (https://docs.docker.com/engine/installation/)
2. Clone this repository
2. Make sure you have a git client installed
3. Clone repository with contents of this project
```shell
git clone git@github.com:jbrazda/ic-sagent-docker.git
```
3. Update the `Dockerfile` if necessary (Location of the SA agent installer might be different for your Informatica CLoud org) You can override the default location by specifying `--build-arg <name>=<value>` in next step
4. Run
4. Update the [Dockerfile](Dockerfile) if necessary (Location of the SA agent installer might be different for your Informatica CLoud org) You can override the default location by specifying `--build-arg <name>=<value>` in next step
5. Run command to build a docker Image
```shell
docker build -t ic-secure-agent:1.0 .
```
To override the download file location use following
The Agent installation location will be dependend on specific Informatica Pod where your org is provisioned
To override the download file location use AGENT_URL argument. typical format for download url is
`https://<pod>.<region>.informaticacloud.com/saas/download/linux64/installer/agent64_install_ng_ext.bin`
```shell
docker build --build-arg AGENT_URL=https://app3.informaticacloud.com/saas/download/linux64/installer/agent64_install.bin -t ic-secure-agent:1.0 .
```
5. execute following command `run -d -h <hostname> --name <agent_name> <image_name:image_tag>`
```shell
docker run -d -h agent1 --name ic-agent1 ic-secure-agent:1.0
```
6. We need to configure the agent to connect it to your Informatica Cloud Org When you running agent for the first time, run following command in the host machine to connect to running agent
```shell
docker exec -it ic-agent1 bash
```
7. Then run following command to configure agent
```shell
./consoleAgentManager.sh configure '<username>' '<password>'
```
8. You can monitor agent running by calling
```shell
docker exec -it ic-agent1 less agentCore.log
docker build --build-arg AGENT_URL=https://na1.dm-us.informaticacloud.com/saas/download/linux64/installer/agent64_install_ng_ext.bin -t ic-secure-agent:1.0 .
```
## 3. Create and run a Container using your Docker Image
Execute following command `run -d -h <hostname> --name <agent_name> <image_name:image_tag>`
```shell
docker run -d -h agent1 --name ic-agent1 ic-secure-agent:1.0
```
If you want to make certain ports available on your host like ability to call Secure agent processes or access oProcess engine Database from your host machine map the available exposed ports using th -p option of the docker run command
Stop the container using a `docker stop <container_name` i.e. docker stop
### . Connect and Initialize Agent
We need to configure the agent to connect it to your Informatica Cloud Org When you running agent for the first time, run following command in the host machine to connect to running agent
```shell
docker exec -it ic-agent1 bash
```
Then run following command to configure agent Prefer using the new method of using username/token instead of password
Using Token
```shell
./consoleAgentManager.sh configureToken '<username>' '<token>'
```
Using Password
```shell
./consoleAgentManager.sh configure '<username>' '<password>'
```
You can monitor agent logs running by
```shell
docker exec -it ic-agent1 less agentCore.log
```
