Jenkins JDK17 Docker still using JDK9?

jonetta last edited by
I installed docker for Jenkins JDK17
```
docker pull jenkins/jenkins:jdk17
```
Reason being I run a single node (I know isn't the best practice, but for trying out) and my target application is also a Java build.

Now, the issue is when I checked the version in a build, it is still Java 9 Not 17! Results in build failures.
```
+ java -version
java version "9.0.4"
Java(TM) SE Runtime Environment (build 9.0.4+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.4+11, mixed mode)
```
How can I get JDK 17 so that I can build my application using Jenkins Docker?

Actually looks like I haven't done a great build-setup here. The way to correctly do this is not trying to change the default JDK (even though I still think there's an issue in the Docker..). What really required is a "Tool" section under JDK section for the builds to work with the custom JDK. So the notion from Jenkins, the Agent JDK is what I need, and not to worry about the Controller JDK really.

A great video that I came across that helped:

You are having problems with the keys and the layout if..elseIn this first passage of code:if(!isDamaged) { else if(dir==left_dir){ g.drawImage(leftPlayer[index], this.getX()-Camera.x,this.getY()-Camera.y,null); } else { g.drawImage(playerDamageLeft, this.getX() -Camera.x,this.getY()- Camera.y,null); } } else if is inside the firstif, then there should be else, the corrected version would be: if(!isDamaged) { if(dir==left_dir){ g.drawImage(leftPlayer[index], this.getX()-Camera.x,this.getY()-Camera.y,null); } else { g.drawImage(playerDamageLeft, this.getX() -Camera.x,this.getY()- Camera.y,null); } } The same is happening in the last block

If you have an apk file, the most likely of it will be the use of the code fusing, which makes it impossible to study the annex code. (Inexperienced developers sometimes disable this function). I don't know anything about the https, I'm sorry.

have anyone tried this scenario (gitlab runner + docker on Windows) before, and have some feedback if it works or not? I installed and registered a GitLab Runner on my Windows 10 laptop following the instructions from GitLab Install GitLab Runner on Windows At first, I had trouble pulling the Windows container image: PS C:\GitLab-Runner> docker pull mcr.microsoft.com/windows/servercore Using default tag: latest Error response from daemon: manifest for mcr.microsoft.com/windows/servercore:latest not found: manifest unknown: manifest unknown PS C:\GitLab-Runner> docker pull mcr.microsoft.com/windows/servercore:1809 1809: Pulling from windows/servercore no matching manifest for linux/amd64 in the manifest list entries PS C:\GitLab-Runner> After selecting the "Switch to Windows containers" option in my Windows Docker (in the top-level menu that opens from the Docker icon in the toolbar), I was able to docker pull the Windows servercore image. However, I was unable to run GitLab Runner on my fully patched and updated Windows laptop: ERROR: Preparation failed: unsupported Windows version: Windows 10 Pro Version 1909 ... It's too new! As I read GitLab's Windows version support policy, GitLab should support 1909 for 18 months; but obviously that is not the case yet. 1903 is the most recent supported version. However, as of January 2020, GitLab has Windows Shared Runners (beta) I tried that and it works. Example .gitlab-ci.yml: my_job: script: systeminfo tags: - windows Is my plan of decreasing Jenkins usage and using more Gitlab runner (for this project at least) feasible? Sounds good to me. Do you have a better approach on how can I improve to a scalable Windows project CI/CD process, other than using gitlab runner + docker? No. I think you're on the right path.

Why should you do port mapping for docker containers?

TL;DR There are a number of use cases for port mapping, but for DevOps at scale the primary reason is generally to enable mapping well-known service ports to available ports on the host. This matters when you're running large numbers of containers that use the same port by default, and you don't want to manually assign or track alternative port numbers. A Very Short Port Primer As a general rule, a port can only map to a single service or process on each host (multiplexing ports and multi-port services are something of an exception). Only 65,536 ports are available for services to bind, with the lowest 1,024 generally reserved for binding by the root user. Services also typically bind to well-known ports such as 22, 53, or 5432 to make the service easy to find. All of these issues matter, but it's often the last issue that typically concerns Docker hosts most. Mapping Container Ports Imagine that you have multiple PostgreSQL containers on a single host. By default, each wants to bind to port 5432 as its default. While you could certainly modify each container or run-command to bind the container's service to a unique host port, this quickly becomes a hassle at scale. Instead, Docker and other container managers make it easy to map ports between the host OS and the container. For example: # launch three PostgreSQL instances for i in {1..3}; do docker run --rm -d -P postgres:alpine done # show port mappings for each container docker container ls -q --filter="ancestor=postgres:alpine" | xargs -n1 docker port 5432/tcp -> 0.0.0.0:32773 5432/tcp -> 0.0.0.0:32772 5432/tcp -> 0.0.0.0:32771 This shows that you have three instances of PostgreSQL, all happily listening on the default port of 5432 inside their containers. However, each instance is listening on a different port (32771, 32772, and 32773) on the Docker host! At scale, you would typically use DNS, autodiscovery, linking, or container networking to help clients and applications find the right PostgreSQL instance to connect with. With just a few instances running, parsing docker ps may be sufficient for your needs. Your specific use case may vary.

In the DEV job you need to archive the artifacts you want to transfer (post build operation -> archive artifacts). In the QA job you need to Copy Artifacts from a different job, select your DEV job name, and select latest successful.

I found out how to do it without pipeline. It only has to do with command line script: start "" C:\MyApp\MyApp.exe >> text.txt This call is asynchronous (i.e., the command line won't wait for MyApp.exe to return). If you want it to wait, you can use the /w flag, like this: start /w "" C:\MyApp\MyApp.exe >> text.txt

Well... apparently it is not possible to read the network profiles saved on the device unless it is rooted (root), otherwise it would be a security issue. Troubleshooting is creating an app of "Keychain" where the user himself provides the network profile information and this information is saved in a database and subsequently when importing the add backup to supplicant profiles through class methods WifiManager ( https://developer.android.com/reference/android/net/wifi/WifiManager.html )In that case I will close the topic, anyone who knows any alternative can comment.

The easiest way is not to handle this information)) You will get tired of such useless information like containers restarts. Anyway, there is couple of tools to monitor docker with prometheus: Google cadvisor Docker experimental prometheus metrics But it requires installation of prometheus, alert-manager, find metrics for triggering and set up alert rules. Or maybe try to find zabbix tool for monitoring docker containers.

Yes, docker containers when they are running can take up some space as per your workload and application but as mentioned in the other answers - containers are built over layered filesystem therefore only extra space they consume is from some file/object they create/download during runtime which is not the part of base image like some debug log files, etc. For ex. - When you run 100 containers of a base image of size 1GB, docker will not consume 100 GB of disk space as it leverages layered filesystem and top immutable layer is shared across all containers of same image. When you stop and remove (yes!, remove explicitly or use --rm flag with docker run command) a container then it's space is reclaimed. To check space used by containers (and other objects), you can use: $ docker system df and for detailed info. use verbose flag $ docker system df -v Initially when you start a container the SIZE column will show 0B but as soon as you start writing to the disk SIZE will change. EDIT: added more info. as suggested by @Benjamin in comments

If this is not possible is there any other way without duplicating the 100GB for each jenkins job? To avoid frequent clones of the repository, you can put a single clone of the repository on-disk on your executor nodes outside of the normal workspace path. Then, in your Jenkins job, you can cd to that directory with the dir step, update the repo, and checkout the branch you want, e.g.: dir('/path/to/repo') { sh('git fetch --all') sh('git checkout origin/lineage-16.0') // your build steps here } However, this has the major drawback that the one repo will be shared across all of your jobs, which means you cannot run those jobs in parallel without risking corruption. It sounds like running jobs in parallel was one of your requirements, so this may be a no-go. You could probably get parallel builds to work by using a copy-on-write filesystem so that the repo appears to be in multiple independent directories but only actually has to be cloned once, but I've never tried something like this, so I can't say how well it would work.

Heritage mapping via notesThis is a very common question and most of the time it is indicated to use an embroidery based on inheritance. For example https://stackoverflow.com/questions/3505866/how-to-map-one-class-to-different-tables-using-hibernate-jpa-annotations gives us the basis for the following example:@MappedSuperclass public class ConsultorBase { /* código da classe vai aqui */ } @Entity @Table(name="TB_Consultor") public class Consultor extends ConsultorBase { ... } @Entity @Table(name="TB_ConsultorHistorico") public class ConsultorHistorico extends ConsultorBase { ... } XML mappingIn other answers ( https://stackoverflow.com/questions/4997950/map-two-identical-tables-same-schema-to-same-entity-in-hibernate and https://stackoverflow.com/questions/5215471/how-to-map-2-identical-tables-same-properties-to-1-entity ) It is suggested to use a separate XML file to map the entity. That way you don't need one superclass.Example of mapping:<class name="Consultor" table="TB_Consultor" entity-name="Consultor"> ... </class> <class name="Consultor" table="TB_ConsultorHistorico" entity-name="ConsultorHistorico"> ... </class> So depending on the type of entity you need, you call the appropriate methods of the session, such as the method http://docs.jboss.org/hibernate/annotations/3.5/api/org/hibernate/Session.html#save%28java.lang.String,%20java.lang.Object%29 :session.save("Consultor", consultor); Or: session.save("ConsultorHistorico", Historico); A http://docs.jboss.org/hibernate/core/3.2/reference/en/html/mapping.html#mapping-entityname , which inspired the example above, says that in order to make the disambiguation, we need to use the entity name, both in XML and in the parameter.This response was based (but well adapted) of the original https://stackoverflow.com/questions/16755260/hibernate-two-tables-per-one-entity .

The "official" nginx image has a specific path where it looks for files. You can either copy a file into the image by creating a new image from it or mount your files into this path as a volume. To copy files, have a folder with your index.html and a Dockerfile that looks like this: FROM nginx COPY index.html /usr/share/nginx/html Then build a new image with docker build -t my-nginx . To start a container with your own files as a volume, you can run the container like this: docker run -p 8080:80 -v ${PWD}:/usr/share/nginx/html nginx All the files in your current folder (including the index.html) will now be available via http://localhost:8080/index.html. Most of this information is covered in the documentation for the image at https://hub.docker.com/_/nginx
