I have a pre-existing golang project with the a following folder structure (minimized the folder for readability).
- postgre
- service.go
- cmd
- vano
- main.go
- vanoctl
- main.go
vano.go
Now since my project web server is in ./cmd/vano I need to create a custom Buildfile and Procfile. So I did that
Here is my Buildfile
make: ./build.sh
build.sh file:
#!/usr/bin/env bash
# Install dependencies.
go get ./...
# Build app
go build ./cmd/vano -o bin/application
and finally my Procfile:
web: bin/application
So now my folder structure looks like this:
- postgre
- service.go
- cmd
- vano
- main.go
- vanoctl
- main.go
vano.go
Buildfile
build.sh
Procfile
I zip up the source using git:
git archive --format=zip HEAD > vano.zip
And upload it to AWS Beanstalk. How ever I keep getting errors and AWS errors don't seem to be the most read. Here is my error
Command execution completed on all instances. Summary: [Successful: 0, Failed: 1].
Error Message

Another approach here instead of using a procfile etc would be to cross-compile your binary (usually pretty painless in go) and upload it that way, as per the simple instructions in the guide:
http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/go-environment.html
You can just compile it locally with:
GOARCH=amd64 GOOS=linux go build -o bin/application ./cmd/vano
Then upload zip of the application file and it should work, assuming your setup only requires this one binary to run.

We run these two commands (the first one is async and the other runs synchronously)
#async BUT does something funky and doesn't run the Dockerfile image as-is
gcloud alpha builds triggers run staging-deploy --branch master
# sync BUT runs the image the way it's supposed to run!!!
gcloud builds submit --config cloudbuild.yaml
both are using our cloudbuild.yaml
steps:
- name: gcr.io/$PROJECT_ID/continuous-deploy
args: ['${_SERVICE}', '${_DOWNLOAD_URL}']
timeout: 1000s
substitutions:
_SERVICE: none
_DOWNLOAD_URL: none
timeout: 1100s
Our Dockerfile is very very simple
FROM gcr.io/google.com/cloudsdktool/cloud-sdk:alpine
RUN mkdir -p ./monobuild
COPY . ./monobuild/
WORKDIR "/monobuild"
#NOTE: This file in google cloud build trigger MUST be in root of monorepo BUT I don't know why
#NOTE: This command receives any arguments to docker
#ie. for "docker run {image} {args}", it receives the args
ENTRYPOINT ["./downloadAndExtract.sh"]
Sooo, when I run the SECOND command, it completely uses the docker image obeying the Dockerfile. When I run the first command, it's ignoring all my Dockerfile stuff and trying to run scripts in my git repo(which is very frustrating and not what I want).
We HAD this directory structure
- gitroot
- stagingDeploy
- Dockerfile
- deployStaging.sh # part of Dockerfile
- cloudbuild.yaml
- prodDeploy
- Dockerfile
- prodDeploy.sh #part of Docker file
- cloudbuild.yaml
Of course, only the second command works with this directory structure. The first command CANNOT find deployStaging.sh UNTIL we ln -s stagingDeploy/deployStaging.sh from our gitrepo root and we have around 5 deploy directories and now our git repo root is fully polluted.
It is to say the least very frustrating and we are not sure how to clean this up so prodDeploy contains all the prod deploy scripts and staging, the staging ones and get rid of all root files.
Of course, we now have a corrupted git repo directory structure with a whole slew of files in the root directory from various different builds(sometimes conflicting on accident as files get the same names sometimes).
EDIT: Not really much to share on configuration of twitter as each one just points to the yaml file is all like so

I recently was able to get my Laravel app deployed using codepipeline on Elastic Beanstalk but ran into a problem. I noticed that my routes where failing because of php.conf Nginx configuration. I had to add a few lines of code to EB's nginx php.conf file to get it to work.
My problem now was that after every deployment, the instance of the application I modified the php.conf file was destroyed and recreated fresh. I wanted a way to dynamically update the file after every successful deployment. I had a version of the file I wanted versioned with my application and so wanted to create a symlink to that file after deployment.
After loads of research, I stumbled on appDeploy Hooks on Elastic Beanstalk that runs post scripts after deployment so did this
files:
"/opt/elasticbeanstalk/hooks/appdeploy/post/91_post_deploy_script.sh":
mode: "000755"
owner: root
group: root
content: |
#!/usr/bin/env bash
sudo mkdir /var/testing1
sudo ln -sfn /var/www/html/php.conf.example /etc/nginx/conf.d/elasticbeanstalk/php.conf
sudo mkdir /var/testing
sudo nginx -s reload
And this for some reason does not work. The symlink is not created so my routes are still not working..
I even added some mkdir so am sure the commands in that script runs, none of those commands ran because none of those directories where created.
Please note that if I ssh into the ec2 instance and run the commands there it works. That bash script also exists in the post directory and if I manually run in on the server it works too.
Any pointers to how I could fix this would be helpful. Maybe I am doing something wrong too.
Now I have gotten my scripts to run by following this. However, the script is not running. I am getting an error
2020/06/28 08:22:13.653339 [INFO] Following platform hooks will be executed in order: [01_myconf.config]

I tried to follow this forum post here to make my file executable by adding to my container command a new command like so:

I am still running into the same issue. Permission denied
Sadly, the hooks you are describing (i.e. /opt/elasticbeanstalk/hooks/appdeploy) are for Amazon Linux 1.
Since you are using Amazon Linux 2, as clarified in the comments, the hooks you are trying to use do not apply. Thus they are not being executed.
In Amazon Linux 2, there are new hooks as described here and they are:
prebuild – Files here run after the Elastic Beanstalk platform engine downloads and extracts the application source bundle, and before it sets up and configures the application and web server.
predeploy – Files here run after the Elastic Beanstalk platform engine sets up and configures the application and web server, and before it deploys them to their final runtime location.
postdeploy – Files here run after the Elastic Beanstalk platform engine deploys the application and proxy server.
The use of these new hooks is different than in Amazon Linux 1. Thus you have to either move back to Amazon Linux 1 or migrate your application to Amazon Linux 2.
General migration steps from Amazon Linux 1 to Amazon Linux 2 in EB are described here
Create a folder called .platform in your project root folder and create a file with name 00_myconf.config inside the .platform folder.
.platform/
00_myconf.config
Open 00_myconf.config and add the scripts
files:
"/opt/elasticbeanstalk/hooks/appdeploy/post/91_post_deploy_script.sh":
mode: "000755"
owner: root
group: root
content: |
#!/usr/bin/env bash
sudo mkdir /var/testing1
sudo ln -sfn /var/www/html/php.conf.example /etc/nginx/conf.d/elasticbeanstalk/php.conf
sudo mkdir /var/testing
sudo nginx -s reload
Commit your changes or reupload the project. This .platform folder will be considered in each new instance creation and your application will deploy properly in all the new instances Amazon Elastic beanstalk creates.
If you access the documentation here and scroll to the section with the title "Application example with extensions" you can see an example of the folder structure of your .platform folder so it adds your custom configuration to NGINX conf on every deploy.
You can either replace the entire nginx.conf file with your file or add additional configuration files to the conf.d directory
Replace conf file with your file on app deploy:
.platform/nginx/nginx.conf
Add configuration files to nginx.conf:
.platform/nginx/conf.d/custom.conf
When I deploy the app, it runs fine on first install. But any following eb deploy procedures fail with an error that: go.mod was found, but not expected.
Is there a specific configuration I have to set for deploying with Go modules?
I switched to Dockerizing the app and deploying that way, which works fine. But it sounds a bit cumbersome to me as AWS Elastic Beanstalk provided specific Go environments.
You can work with go modules.
build.sh
#!/usr/bin/env bash
set -xe
# get all of the dependencies needed
go get
# create the application binary that EB uses
go build -o bin/application application.go
and override GOPATH to point to $HOME which defaults to /var/app/current as given in the EB configuration management dashboard.
.ebextensions/go.config
option_settings:
aws:elasticbeanstalk:application:environment:
GOPATH: /home/ec2-user
I had the same problem, I was finally able to fix it adding this line in my build.sh script file:
sudo rm /var/app/current/go.*
So it is like this, in my case:
#!/usr/bin/env bash
# Stops the process if something fails
set -xe
sudo rm /var/app/current/go.*
# get all of the dependencies needed
go get "github.com/gin-gonic/gin"
go get "github.com/jinzhu/gorm"
go get "github.com/jinzhu/gorm/dialects/postgres"
go get "github.com/appleboy/gin-jwt"
# create the application binary that eb uses
GOOS=linux GOARCH=amd64 go build -o bin/application -ldflags="-s -w"
I was trying to setup a build trigger for an kotlin app that is build using gradle. For that I put together the following Dockerfile:
FROM gradle:jdk8 as builder
WORKDIR /home/gradle/project
COPY . .
WORKDIR ./Kuroji-Eventrouter-Server
RUN gradle shadowJar
FROM openjdk:8-jre-alpine
WORKDIR /app
COPY --from=builder /home/gradle/project/Kuroji-Eventrouter-Server/build/libs/kuroji-eventrouter-server-*-all.jar kuroji-eventrouter-server.jar
ENTRYPOINT ["java", "-jar", "kuroji-eventrouter-server.jar"]
And that file works on my machine with docker build and it starts normally on google container registry however during the RUN gradle shadowJar task it crashes with some gradle error:
Step 5/9 : RUN gradle shadowJar
---> Running in ddd190fc2323

I tried building the Image on docker HUB and the same thing happend: https://hub.docker.com/r/usbpc/kuroji-eventrouter-server/builds/bnknnpqowwabdy82ydxiypc/
This is very confusing to me as I thought containers should be able to run anywhere and not depend on the enviroment. What can I do to make google build my container?
The problem was a file permission problem. Using the --stacktrace option I found that the gradle process didn't have permissions to create a folder inside the sources.
The solution I would like to do is use the --chown=gradle:gradle option on the COPY instruction, unfortunatly this it not supported in the google cloud yet.
So the solution is to add USER root before executing the gradle build.
I try to support the use of the webp format with EB, however it's not working as expected...
I created a .config file in .ebextensions with this:
commands:
01-command:
command: wget https://storage.googleapis.com/downloads.webmproject.org/releases/webp/libwebp-0.5.0.tar.gz
02-command:
command: tar xvzf libwebp-0.5.0.tar.gz
03-command:
command: cd libwebp-0.5.0
04-command:
command: ./configure
05-command:
command: make
06-command:
command: sudo make install
But when deploying I got this error:
ERROR: Command failed on instance. Return code: 127 Output: /bin/sh: ./configure: No such file or directory.
Am I doing something wrong?
(environment: 64bit Amazon Linux 2015.09 v2.0.6 running PHP 5.6)
You need to execute the install post deployment. AWS hasn't really documented how to execute commands post deployment, so I'll do so here.
commands:
create_post_dir:
command: "mkdir /opt/elasticbeanstalk/hooks/appdeploy/post"
ignoreErrors: true
files:
"/opt/elasticbeanstalk/hooks/appdeploy/post/99_install_libwebp.sh":
mode: "000755"
owner: root
group: root
content: |
#!/usr/bin/env bash
. /opt/elasticbeanstalk/support/envvars
cd $EB_CONFIG_APP_CURRENT
wget https://storage.googleapis.com/downloads.webmproject.org/releases/webp/libwebp-0.5.0.tar.gz
tar xvzf libwebp-0.5.0.tar.gz
cd libwebp-0.5.0
sudo ./configure
sudo make
sudo make install
As I mentioned, AWS has not really documented that you can actually execute scripts on ElasticBeanstalk post deployment. If you talk a look in the eb-commandprocessor.log file you will see that eb looks for AppDeployPreHook (4 of 6) and AppDeployPostHook (1 of 2). It will look something like this:

That little "AppDeployPostHook" tells us that it is searching for scripts to run post deployment. You can find the eb deployment scripts in the /opt/elasticbeanstalk directory on the server, and if you ssh in and ls on that directory you'll find hooks, which is what we're looking for, and if you cd hooks you'll find the appdeploy directory, cd appdeploy and then ls and you'll get two directories pre and enact. This seems mundane but is really great, because now we know where eb is looking for scripts it's running. Since the AppDeployPreHook scripts are executing from the "pre" directory we know that we'll need a "post" directory to execute a command post deployment with that AppDeployPostHook that eb is running. Now that we know what to do, we can start writing our commands.
create_post_dir First step is to actually going to create the "post" directory on the server using the mkdir command. mkdir "/opt/elasticbeanstalk/hooks/appdeploy/post" will do that for us, so we'll create that as the command.
files The files config allows us to create a file in a directory via ElasticBeanstalk. Pretty convenient for our purposes! The first line of the files action gives us the name of the file to create. We'll create a shell script to execute out commands, and you can call it whatever you want, but I'd start with 99 and go onwards. We'll call this shell script that we're creating "99_install_libwebp.sh".
File settings The next three lines set the file settings. Make sure root owns them and that there 000755'd.
File Contents This is the content of the file we're creating. Straight forward. Put your shell script in there and you're good to go.
Load environment vars We opted to load the eb environment variables so our script can know where the current version of the app is. It's usually in /var/app/current but it could be elsewhere depending on a variety of factors. We'll use the environment variables to make life a bit easier for us.
Change to our current app directory We're going to cd to our current app directory so we can do what we we're here to do.
Get the package we want use wget to get the libwebp we want
Unpack the package self explanatory
Change to the package directory Now that we've unpacked the package we can change to the package directory.
Do what we need to do We can now run our ./configure, make, and make install.
That's it. You can use the stealthy AppDeployPostHook to run pretty much any post deployment command that you need. Super useful if you need to install packages, restart services, or do anything else post deployment.
I added the code I deployed to Github, for easy reference too. https://github.com/hephalump/testphp
Note: I did this successfully running a slightly different environment. I used ElasticBeanstalk to deploy a new PHP application using the latest environment version which is PHP 5.6 on 64bit Amazon Linux 2016.03 v2.1.0; the environment type that you are using was not available as an option to me... Actually, this was the only version with PHP 5.6 that was available to me so I went with that.
