将n8n部署到Heroku
将n8n部署到Heroku
提问于 2020-04-15 11:53:22
我在通过Docker注册中心将n8n部署到Heroku时遇到了问题，并且无法确定我做错了什么。任何帮助都将不胜感激。
手动提供Postgres版本11：
heroku addons:create heroku-postgresql:hobby-dev --version=11 -a my-appDockerfile：
FROM n8nio/n8nheroku.yml：
setup:
#addons:
# - plan: heroku-postgresql:hobby-dev
# version: 11
# as: DATABASE
config:
SUBDOMAIN: "my-app"
DOMAIN_NAME: "herokuapp.com"
NODE_ENV: "production"
TZ: "Europe/Berlin"
GENERIC_TIMEZONE: "Europe/Berlin"
N8N_HOST: "${SUBDOMAIN}.${DOMAIN_NAME}"
N8N_PORT: "${PORT}" #each app in heroku gets randomly assigned IP on start
N8N_PROTOCOL: "https"
N8N_ENCRYPTION_KEY: "mysupersecretkey"
WEBHOOK_TUNNEL_URL: "https://${SUBDOMAIN}.${DOMAIN_NAME}/"
VUE_APP_URL_BASE_API: "https://${SUBDOMAIN}.${DOMAIN_NAME}/"
DB_TYPE: "postgresdb"
DB_POSTGRESDB_HOST: "dbhost"
DB_POSTGRESDB_DATABASE: "dbname"
DB_POSTGRESDB_PORT: 5432
DB_POSTGRESDB_USER: "dbuser"
DB_POSTGRESDB_PASSWORD: "dbpass"

您需要稍微修改Dockerfile和entrypoint脚本。正如@VxJasonxV exec所提到的，sudo特权在Heroku上是不允许的。
这是我对集装箱的实现-
Heroku yml -
build:
docker:
web: DockerfileDockerfile -
FROM node:12.16-alpine
# pass N8N_VERSION Argument while building or use default
ARG N8N_VERSION=0.62.1
# Update everything and install needed dependencies
RUN apk add --update graphicsmagick tzdata
# Set a custom user to not have n8n run as root
USER root
# Install n8n and the also temporary all the packages
# it needs to build it correctly.
RUN apk --update add --virtual build-dependencies python build-base && \
npm_config_user=root npm install -g n8n@${N8N_VERSION} && \
apk del build-dependencies
# Specifying work directory
WORKDIR /data
# copy start script to container
COPY ./start.sh /
# make the script executable
RUN chmod +x /start.sh
# define execution entrypoint
ENTRYPOINT ["/start.sh"]入口点脚本
#!/bin/sh
# check if port variable is set or go with default
if [ -z ${PORT+x} ]; then echo "PORT variable not defined, leaving N8N to default port."; else export N8N_PORT=$PORT; echo "N8N will start on '$PORT'"; fi
# kickstart nodemation
n8n我已经创建了一个Github回购为同样，请看，我已经添加了一个良好的描述自述文件，希望它有帮助。https://github.com/sarveshpro/n8n-heroku

这个su-exec错误听起来像是n8n需要根/提升的特权，这是您在Heroku上没有得到的。如果您必须以某种方式配置它以严格地运行“非特权”，请这样做。
