10.3.1 How to create a Docker image and Podman image

(1) Prepare the followings under the working directory

The files to be prepared under the working directory are the same as for JP1/IM - Agent. Place the configuration files for an add-on program of IM Exporter under the conf directory. When monitoring script exporter targets in a container, include them in the image in the same way.

Here, type the files to be added to the JP1/IM - Agent directory structure.

working directory/
  + conf/
      + jpc_process_exporter.yml#1
      + jpc_script_exporter.yml#2
      + promitor/#3
          + scraper/#4
              + runtime.yaml#5
              + metrics-declaration.yaml#6
          + resource-discovery/#7
              + runtime.yaml#8
              + resource-discovery-declaration.yaml#9

#1: process exporter configuration file(If changing the settings)

#2: script exporter configuration file(If changing the settings)

#3: promitor configuration file directory(If changing the settings)

#4: promitor scraper configuration file directory(If changing the settings)

#5: promitor scraper configuration file (If changing the settings)

#6: promitor scraper configuration file (If changing the settings)

#7: promitor resource discovery configuration file directory (If changing the settings)

#8: promitor resource discovery configuration file (If changing the settings)

#9: promitor resource discovery configuration file (If changing the settings)

The build procedure to connect to Azure with ServicePrincipal is as follows.

1. In the build procedure described in Building a container environment for integrated agents for JP1/IM - Agent, perform the steps other than step 4 in 10.1.2(6) Setting up Promitor > (b) Configuring authentication information for connecting to Azure and then create the files under the working directory.

2. After starting the container, perform step 4 in 10.1.2(6) Setting up Promitor > (b) Configuring authentication information for connecting to Azure.

3. Start the Promitor service. For details, see Building a container environment for integrated agents for service control.

The following is an example of a Docker file.

FROM oraclelinux:8
:
ENV JP1IMAGENT_ADDON_PROMITOR_ACTIVE "no"#
ENV JP1IMAGENT_ADDON_PROCESS_EXPORTER_ACTIVE "yes" 
ENV JP1IMAGENT_ADDON_SCRIPT_EXPORTER_ACTIVE "no" 
:
CMD [ "/bin/bash", "-c", "/opt/start.sh" ] 

#

If "yes", after the container starts, the following log will be output and the service will have a failure status. If you specify the authentication information and restart, the service will start normally.

Validation failed: Azure authentication is not configured correctly - No identity secret was configured for service principle authentication

The following is an example of a service definition file.

[unix_http_server]
file=/tmp/supervisor.sock   ; the path to the socket file
 :
[program:process_exporter]
command=command-line
directory=/opt/jp1ima/bin
autostart=true
stopwaitsecs=180
