如何为teamcity代理安装附加软件

Question

我通过docker镜像安装了teamcity代理

如何通过brew向该代理添加一些软件？

Answer 1

Dockerized Teamcity代理很可能需要扩展基本映像并使用适当的包管理。

例如，我们使用基于Ubuntu操作系统的teamcity-minimal-agent映像。

以下是扩展Dockerfile的示例，其中包含我们的软件所需的一些基本工具和额外包的安装说明，以及运行"docker in docker"的docker客户端。

此外，它还运行步骤来同步操作系统用户id和用于运行代理的buildagent用户id。

# Custom Dockerfile
FROM jetbrains/teamcity-minimal-agent:2019.2
ARG user_id
ARG docker_group_id
ENV USER_ID=${user_id}
# Set correct environment variables.
ENV LANG C.UTF-8
ENV DEBIAN_FRONTEND noninteractive
# Install basic tools
RUN apt-get update && 
apt-get -y --no-install-recommends install 
dirmngr 
gpg-agent 
software-properties-common 
apt-transport-https 
wget 
zip 
git

# Add key and docker repository
ENV DOCKER_VERSION 18.03.1~ce~3-0~ubuntu
RUN curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
RUN echo "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" > /etc/apt/sources.list.d/docker.list
# Install necessary software
RUN apt-get update
RUN apt-get -y --no-install-recommends install 
docker-ce=${DOCKER_VERSION} 
rsync openssh-client vim python python-dev 
bzip2 nodejs dnsutils sudo
# Install pip and packages
RUN curl -sS 'https://bootstrap.pypa.io/get-pip.py' | python
RUN pip install 
pep8 
requests
# Access and signature for github repositories
COPY <my-gpg-file>.gpg /var/tmp/<my-gpg-file>.gpg
# Pass OS user's id and export it to use in subcontainers
RUN groupmod -g ${USER_ID} buildagent && 
usermod -g ${USER_ID} -G docker buildagent
# Sync docker group id between OS and container
RUN groupmod -g ${docker_group_id} docker
USER buildagent
RUN gpg --allow-secret-key-import --import /var/tmp/<my-gpg-file>.gpg
RUN git config --global user.email "[e-mail]" && 
git config --global user.name "Teamcity Bot" && 
git config --global user.signingkey <my-gpg-key>
USER root

Docker compose使其更易于运行。下面找一个例子。它允许在代理docker容器中运行docker容器，称为"docker中的docker"。

# Docker-compose to run containers
#
# Build images: DOCKER_GROUP_ID=$(getent group docker | cut -d: -f3) USER_ID=$(id -u) docker-compose build
# Start containers: docker-compose up -d
#
version: '2.2'
services:
teamcity-server:
hostname: "teamcity-server"
container_name: "teamcity-server"
build: "."
volumes:
- "/data/teamcity:/data/teamcity:rw"
environment:
TEAMCITY_SERVER_MEM_OPTS: -Xmx1g -XX:ReservedCodeCacheSize=350m
TEAMCITY_LOGS: /opt/teamcity/logs
TEAMCITY_DIST: /opt/teamcity
TEAMCITY_DATA_PATH: /opt/teamcity/data
ports:
- "443:443"
- "80:80"
restart: "always"
teamcity-agent:
hostname: "teamcity-agent-01"
container_name: "teamcity-agent-01"
build:
context: "./teamcity-agent"
args:
user_id: "${USER_ID}"
docker_group_id: "${DOCKER_GROUP_ID}"
image: "teamcity-agent"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock"
- "/var/lib/docker:/var/lib/docker"
- "/opt/share/.composer:/home/buildagent/.composer:rw"
- "/opt/agents:/opt/agents:rw"
environment:
- "SERVER_URL=https://<teamcity-url>"
- "AWS_DEFAULT_REGION=ap-southeast-1"
- "AGENT_NAME=teamcity-agent-01"
- "RUN_AS_BUILDAGENT=true"
privileged: true
restart: "always"
cpus: 1
mem_limit: 1g

这些例子也可以简化很多。
