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.

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 have created a ruby env on amazon elastic beanstalk, but when I try to deploy my rails app from command line using eb deploy I get this error:
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root
users on this machine.
You need to install git to be able to use gems from git repositories. For help
installing git, please refer to GitHub's tutorial at

So, shall I install git at amazon instance bash directly? will this effect autoscaling?
I don't know if you fixed this, but you need to tell Elastic Beanstalk to install git.
In the root directory of your project, add a folder called .ebextensions.
Create a file inside that folder called (something like) install_git.config (the .config is important).
Add the following lines to that file:
packages:
yum:
git: []
Then redeploy your application, and you shouldn't see that error anymore.
I've created a GitHub repo for my simple custom recipe:
my-cookbook/
|- recipes/
|- appsetup.rb
I've added the repo to Custom Chef Recipes as https://github.com/my-github-user/my-github-repo.git
I've added my-cookbook::appsetup to the Setup "cycle".
I know it's executed, because it fails to load if I mess up the syntax.
This is my appsetup.rb:
node[:deploy].each do |app_name, deploy|
script "install_composer" do
interpreter "bash"
user "root"
cwd "#{deploy[:deploy_to]}/current"
code "curl -sS https://getcomposer.org/installer | php && php composer.phar install --no-dev"
end
end
When I log into the instance by SSH with the ubuntu user, composer isn't installed.
I've also tried the following to no avail (A nodejs install):
node[:deploy].each do |app_name, deploy|
execute "installing node" do
command "add-apt-repository --yes ppa:chris-lea/node.js && apt-get update && sudo apt-get install python-software-properties python g++ make nodejs"
end
end
Node doesn't get installed, and there are no errors in the log. The only references to the cookbook in the log just says:

Am I missing some critical step somewhere? The recipe is clearly recognized and loaded, but doesn't seem to be executed.
(The following are fictitious names: my-github-user, my-github-repo, my-cookbook)
I know you've abandoned the cookbook but I'm almost 100% sure it's because you don't have a metadata.rb file in the root of your cookbook.
Your cookbook name should not contain a dash. I had the same problem, replacing by '_' solved it for me.
If those commands are failing silently, it could be that your use of && is obscuring a failure.
As for add-apt-repository, that is an interactive command. Try using the "--yes" option to answer yes by default, making it no longer interactive.
If you do not execute your command successfully, you will not find the files in the current directory. Check inside the last release folder to see if it had been put there.
It maybe prudent to check if you got the right directory etc setup by changing the CWD to : /tmp
