Dockerfile for Apache Traffic Server (ATS)

Get Social!

Apache Traffic Server is an enterprise-grade proxy and caching server initially developed by Yahoo, then later made open source and managed by the Apache Foundation.

The below code is a Dockerfile that will download and build ATS on the latest Ubuntu base image. Currently, we’re using Apache Traffic Server version 8.0.5, but if you’d like to use a different version or check for a later version then you’ll need to replace the curl command with one of the downloads available from here.

Create a new folder on your Docker host and add the below text to the dockerfile.

mkdir ats
vi ats/dockerfile
FROM ubuntu:latest
# Update the package repository
RUN set -x \
 && DEBIAN_FRONTEND=noninteractive apt-get update \

    # Clean-up

        curl \

        tcl-dev \
        libboost-dev \
 && apt-get clean \
 && rm -rf /tmp/* /var/lib/apt/lists/*

RUN ln -s /usr/local/etc/trafficserver /etc/trafficserver

ENTRYPOINT ["/usr/local/bin/traffic_server"]

To build the Apache Traffic Server image, cd into the ats directory and issue the build command. The period (.) at the end of the build command is there on purpose – make sure you include it in your build command.

cd ats
docker build -t ats .

The build will take a few minutes, depending on your hardware, but will return you to the command line once completed.

Run your dockerfile and ATS will be available on port 8080, however, you’ll need to configure it as required. The config, such as remap.conf, is contained in /etc/trafficserver

CockroachDB systemd script

Get Social!

This is a simple systemd script for CockroachDB. It works for single node installations or multiple nodes, however you’ll need to manually join each node to the cluster before using the systemd script. 

Create the systemd file and add the following content:

vi /etc/systemd/system/cockroach.service


ExecStartPre=/bin/bash -c "test -f /etc/cockroachdb/hosts && (/bin/systemctl set-environment JOIN_SWITCH=--join=$(test -f /etc/cockroachdb/hosts && cat /dev/null /etc/cockroachdb/hosts)) || exit 0"
ExecStartPre=/bin/bash -c "test -f /etc/cockroachdb/host && (/bin/systemctl set-environment HOST_SWITCH=--host=$(test -f /etc/cockroachdb/host && cat /dev/null /etc/cockroachdb/host)) || exit 0"

ExecStart=/usr/local/bin/cockroach start --certs-dir=/etc/cockroachdb/certs \
                                         --store=/var/data/cockroachdb/ \
                                         --cache=.40 \
                                         --max-sql-memory=.30 \
                                         --external-io-dir=/tmp/cockroachdb/externalio \
                                         --temp-dir=/tmp/ \
                                         --port=26257 \
                                         --http-port=7005 \
                                         --logtostderr=ERROR \
                                         --log-dir=/var/logs/cockroachdb \
                                         $JOIN_SWITCH $HOST_SWITCH

ExecStop=/usr/local/bin/cockroach quit --certs-dir=/etc/cockroachdb/certs

Note that there are several paths specified in the above file which may need to be tailored to your installation requirements.

Run the following to enable the service on system start, and to start the CockroachDB service.

systemctl enable cockroach # enable on startup
systemctl start cockroach  # start CockroachDB

If your host belongs to a cluster, create a hosts file containing the hosts of other nodes in your cluster that will be read when starting your local node. For multiple nodes, use a comma to separate each hostname and port combination.

vi /etc/cockroachdb/hosts,
