MI Slackbot deployment
This article provides a step-by-step instruction on how to install the MI Slackbot on your server and update the bot to a newer version.
The MI Slackbot is realized as part of the MI Slack App functionality and works in conjunction with the Slack App built as bot on the Slack Side. After the MI Slackbot has been installed on your Server and the Slack App with bot functions has been built in Slack, the two have to be connected (MI Slack App = MI Slackbot + Slack App).
The whole process comprises the following steps:
1. Connect to the server by ssh
- Use ssh firstname.lastname@example.org and replace the zeros with the server IP address.
- When prompted, enter the root password provided by your IT specialist.
2. Download the MI Slackbot installation package
- Depending on the version, you will be given a link to the corresponding MI Slackbot installation package.
- Along with the link, Username and Password will be provided by the MI support team; enter these credentials into the respective fields.
- Confirm your agreement with the Terms and Conditions of the MI Slackbot usage.
- Click [Submit].
This will initiate the download process of the .tar.gz archive (containing all files required to install the system).
3. Operating Systems Supported
The list of supported Operating Systems:
- Debian 7 (wheezy)
- Debian 8 (jessie)
- Red Hat Enterprise Linux 7
- CentOS 6 (depreciated in Release 5.5)
- CentOS 7
- Ubuntu 14.04
3.1. Additional Actions for Operating Systems
If you are using a firewall on the Linux machine, inbound TCP ports 80 and 443 are necessary for the MI Slackbot to work correctly. If they need to be opened, use the following commands:
Examples for iptables:
iptables -A INPUT -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp --sport 80 -m state --state ESTABLISHED -j ACCEPT iptables -A INPUT -p tcp --dport 443 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp --sport 443 -m state --state ESTABLISHED -j ACCEPT
Examples for ufw:
ufw allow 80/tcp ufw allow 443/tcp
Examples for firewall-cmd:
firewall-cmd --zone=public --add-port=80/tcp --permanent firewall-cmd --zone=public --add-port=443/tcp --permanent
4. Unpack the downloaded .tar.gz archive with the following command
tar -xfv MetricInsights-Slackbot-<version_number>.tar.gz
5. Enter the new unpacked folder
6. Initiate the installation process
- The MI Slackbot must have an open access to the web.
- The installation commands below can only be run by a root user.
- The MI Slackbot can be installed on a server with the pre-installed MI application (Version 5.3.0. and beyond).
- The Slackbot installer will not work with an MI application prior to 5.3.0
6.1. Install the MI Slackbot on the same server as the main MI application
6.2. Install the MI Slackbot on a separate server
6.3. Install the MI Slackbot on a DMZ server
The MI Slackbot can also be deployed within a DMZ (Perimeter) network.
As an external-facing app, the MI Slackbot must be accessible from the internet. DMZ deployment allows the Bot app to be reachable from the Public Network, while the data it queries from Metric Insights remains securely locked within a Private Network.
For details, view the Architecture diagram below.
In case there is a connection issue or a WebSocket failure (check for errors with Slack connection test), you will need to:
- Whitelist the following domains: *.slack.com *.slack-msgs.com *.slack-files.com *.slack-imgs.com *.slack-edge.com *.slack-core.com *.slack-redir.net slackb.com edgeapi.slack.com wss-primary.slack.com wss-backup.slack.com wss-mobile.slack.com app.slack.com a.slack-imgs.com b.slack-imgs.com
- Check if your proxy is running SSL decryption. If it is, the proxy must either support WebSockets, or you’ll need to exempt the following domains: *.slack-msgs.com wss-primary.slack.com wss-backup.slack.com wss-mobile.slack.com

To update the MI Slackbot:
- Download the new package
- Extract the archive
- Install it over the old version
