Running Spring Boot in A Docker Container. Containers based deployments are rapidly gaining popularity in the enterprise. One of the more popular container solutions is Docker. Many view containers as virtual machines. Theyre not. Well kind of not. A container is a virtual walled environment for your application. Installing OpenJDK. We will start from installing the OpenJDK. There are two packages that we can install, a JRE and JDK. Those familiar with Java already know what. Big Data Hadoop Tutorials Hadoop 2. 6 Installing on Ubuntu 14. 04 SingleNode Cluster Hadoop 2. 6. 5 Installing on Ubuntu 16. 04 SingleNode Cluster. Its literally a container inside the host OS. Thus your application works like it is in its own self contained environment, but its actually sharing operating system resources of the host computer. Because of this, containers are more resource efficient than full blown virtual machines. You get more bang for your buck running a bare metal machine with a bunch of containers, than you do running a bare metal machine with a bunch of VMs. This is why massive cloud computing companies running 1. Google, Facebook, Netflix, Amazon are all big advocates of containers. Introducing Docker Containers. To help you visualize the difference, here are a couple images provided by Docker. Here is the bloated architecture of a traditional virtual machine environment. A popular solution you can try is Oracles Virtual Box which allows you run a variety of operating systems on your personal machine. I personally use VMWare Fusion to run Windows on my MBP and I still feel a little dirty every time I do. If youve never used either these, I recommend you give them a try. In this graphic, note how each stack has its own Guest OS. Now for comparison, here is the same stack containerized by Docker. Here you can see how each application does not get its own operating system. This is key to why Docker containers are so efficient. Youre not providing a virtual layer mimic the hardware, for the the guest OS to use. And youre not running n1 guest hosts either. Clearly this is more efficient computing. Ive seen estimates in the 1. But like with everything else when it comes to computing performance your mileage may vary. Id expect lightweight linux VMs to be closer to the 1. Windows VMs probably closer to the 2. Windows OS is so bloated in comparison. This leads me to an important distinction about Docker Linux only. Yes, you can run Docker on Windows and OSX but at this time, you can only do so using a VM running in Virtual Box to run a Linux VM. Running Spring Boot in a Docker Container. Introduction. When I first heard about running Spring Boot in a Docker container, I personally thought now why would you want to run a JVM in a VM, on a VM At first glance, it just seemed like a absolutely terrible idea from a performance standpoint. I doubt if any of these solutions will ever match the performance of a JVM running on a bare metal installation of Linux. But, Ive shown above, running a Spring Boot application in a Docker container should have minimal performance impact. Certainly less of an impact than running in a VM. Which is exactly what youre doing running applications in any cloud provider see image one above. Installing Docker. Im not going to get into installing Docker on your OS. There is ample documentation about installing Docker in the internet. Going forward, Im going to assume you have Docker installed. Since Docker is Linux based, my focus will be on Linux RHEL Cent. OS. Spring Boot Example Application. For the purposes of this tutorial, lets start with a simple Spring Boot Application. Im going to use the completed application from my Mastering Thymeleaf course. This is a simple Spring Boot web application which is perfect for our needs. If you want to follow this tutorial along step by step, head over to Git. Hub and checkout this Spring Boot project. Be sure to change to the branch spring boot docker start. Building a Spring Boot Docker Image. For us to run Spring Boot in a Docker container, we need to define a Docker image for it. Building Docker images is done through the use of Dockerfiles. Dockerfiles are basically a manifest of commands we will use to build and configure our docker container. To configure our Docker image to run our Spring Boot application, we will want to Start with the latest Cent. OS image from Docker Hub. Install and configure Oracle Java. Install the Spring Boot artifact our executable JAR file. Run the Spring Boot application. Im using Cent. OS for its compatibility with RHEL, which is probably the most popular linux distribution used by enterprises. And Oracles Java, mainly for the same reason. Create Our Dockerfile. In our Maven project, we need to create our Dockerfile. In. srcmaindocker create the file. Dockerfile . NOTE As a Java developer you may be tempted to create the file as Docker. File. Dont do this. The Maven Plugin we cover later wont see your file if its Camel. Case. I learned this lesson the hard way. Cent. OSWell start our Docker image off by using the Cent. OS image from Docker hub. Dockerfile. Installing Oracle Java. The following lines in our dockerfile will install wget into the image using the yum package installer, download the Oracle Java JDK from Oracle using wget, then configure Java on the machine.

Docker will map this to to varlibdocker on the host system. This is the directory Spring Boot will configure Tomcat to use as its working directory. The. ADD command adds the Spring Boot executable Jar into our Docker image. The. RUN command is to touch the JAR and give it a modified date. The. ENTRY point is what will run the jar file when the container is started. I learned about these configuration settings from a post from the Pivotal team here. Dockerfile. ADD mavenmyapp 0.

For the last 3 days I occasionally get this window in front of me Do you want to ContinueThe web sites certificate has been verified. Website https javadl esd secure. Note The certificate is valid and has been used to verify the identity of this website. This popup message is not related to my Pale Moon browser. I deactivated Java plugins in any browser. This is some background service that connects to a server not any user made query. I think its related to installing the Java SE development Kit. Earlier, when I only had the Java runtime environment without the development kit, I did not get asked this question at all. I guess it is a certificate confirmation for a Java update server query. But it bugs me, that this window does not explain itself what its for. Also its in always on top mode and distracts me while doing something else. Can somebody confirm my guess The screenshot also contains my Pale Moon plugin settings in the background to indicate that I havent activated any Java web plugins. Windows 7 x.

Hack an Easy Button for Quick Slack Alerts. Working with headphones on usually means youd rather not be bothered, but sometimes it means youre just listening to something while you work. If you want to be available despite your cans being on, why not build your own alert button Enter developer Nick Sypteras, who wanted to solve the problem of coworkers requesting his attention while his headphones were on. Working in a cubicle, he wrote, Theres no way for a visitor to my desk to get my attention other than by waving their hand in my face, making loud noises behind me, etc. So he broke out the soldering iron, a Staples Easy Button, and an Adafruit microcontroller.

Android Oreo has at last been fully baked, and given a name, and is now rolling out to those of you with a Pixel, Pixel XL, Nexus 5. X, Nexus 6. P, or Pixel C Google says a bunch of other handsets will get Oreo by the end of the year too. So what can you look forward toMacOS High Sierra is heading your way on September 25, and while its not packed with major new features to transform your Mac computing experience, there are some. Here are the new tricks youll be able to play around with when your update arrives. Use picture in picture everywhere. The You. Tube app for Android has been able to shrink videos down into a little window for some time, but now you can do it in any app, with any other app in the backgroundas long as app developers decide to support it. It works in Chrome for Android already Just make any video full screen, hit the Home button, and hey presto youve got a PIP window. Turn on notification badges. Android users no longer need to look quite as enviously at their i. Phone toting friends, because Oreo lets apps display notification badges on their home screen icons too From Settings tap Apps notifications then Notifications to find the toggle switch. The badges need to be enabled by developers too, so you might not see them in all apps straight away. Manage notification priorities. Android Oreo lets you manage notifications in more detail using notification channels, so you can categorize the ones you want to see and the ones you dont, even within notifications from the same appswipe right on a notification then tap the cog icon to see the options, or dive into the settings for a particular app to see what the options are. For example, some of your group chats in a messaging app might have permission to buzz and light up your phone, while others just display a silent alert. Setting up parental controls can be very beneficial for your family. It gives you the ability to manage how your children use their device and gives you peace of mind. How to Set Up Parental Controls in Windows 8. If you have children who use your computer under their own accounts, you can set up parental controls in Windows 8 to. CCleaner automatically deletes unneeded files and Windows Registry entries. It can also detect duplicate files, securely wipe a storage device, and act as an. Again this is something developers need to enable on their side as well, so you wont see it in every app straight away, and its the app developers who set the different levels of categories or channels. Enjoy better security. Google Play Protect is being promoted alongside Android Oreo, though its actually rolling out through Google Play Services to older devices toohead to Settings, Google, then Security to see if youve got it. The service scans your incoming and installed apps for malware, sending you notifications if it spots anything suspicious or needs to take action. Snooze notifications until later. Another notification upgrade you can snooze notifications until youre ready to deal with them, rather than dismiss them once and never see them again. Swipe to the right on an alert on the lock screen or in the notification drawer, tap the clock icon, and edit the time delay if needed. This works on all apps straight out of the box with Android Oreo. Save even more battery life. Android has been getting better and better at limiting the background activity of apps when you want to save battery life, and with the launch of Oreo it goes even further, with new rules on what apps can and cant do in the background. A lot of this should happen behind the scenes, so all you will see in theory is your battery lasting for a longer stretch. Play around with new emoji. A new version of Android usually means a bunch of new emojis, and Oreo is no differentin fact, Google has redesigned the entire emoji icon set this time around, so the blobs are out and more regular faces are in. New emojis include a wizard, a dinosaur, a fairy, and an exploding head for when you hear how long your Oreo update is delayed for. Select text more easily. Android Oreo can select text on screen with a bit more intelligenceif you tap and hold on a recognizable bit of text like a phone number, then Android can automatically highlight the whole lot for you. You also get context sensitive shortcuts appearing in the bar above, so if youve picked out an address, for example, one of the links leads to Google Maps. Use new shortcuts in the camera. The camera app bundled with Oreo has a couple of minor tweaks that might make a major difference to your photo and video taking in the future. First, you can double tap on the screen to zoom in 5. Sync all your data across all your devices. Chrome has synced data across devices for a while now, but Android Oreo is expanding that with a new Autofill feature. With your permission, it allows the syncing of app logins, credit card details, addresses and other information between devices and inside apps like your mobile browserLast. Pass is one of the first apps to support the new feature. Play around with an octopus. No Android version would be complete without an Easter egg, though admittedly the one in Android Oreo isnt the most impressive weve ever seen. From Settings, tap System then About phone, then tap Android version until you see the big Android O. Then, tap the O repeatedly before long pressing it to get an octopus that. CCleaner Free download and software reviews CCleaner automatically deletes unneeded files and Windows Registry entries. It can also detect duplicate files, securely wipe a storage device, and act as an alternative to Windows Programs and Features tool for uninstalling software. Pros. One stop shop for junk file cleanup You can clean up a lot of unnecessary files without downloading another app, but its handy to have those cleanup tools a mouse click away. With CCleaner, you just hit the Analyze button and the app will inspect and tidy up storage space hogs, like Web browser caches, temporary files, and Windows log files. Lots of optional settings to customize behavior By default, CCleaner deletes files but doesnt fully erase them. The difference is that a deleted file doesnt immediately disappear it just becomes a section of your storage device that Windows can put other files on. If youre more security minded and want to fully erase unwanted files, CCleaners Analyze writes over them with random ones and zeroes, up to 3. Other settings let you specify browser cookies that you always want to keep, add custom folders for CCleaner to analyze, or exclude other folders. Low key sales pitch The free version of CCleaner doesnt bug you about paying for the premium version, nor does its interface try to trick you into looking at a sales pitch. Cons. Some storage savings is temporary This is not a flaw in CCleaner, just a fact of Web browsing Deleting your browser cache can get rid of gigabytes of files, but your cache will fill up again over time, so that recovered storage space isnt permanent. Also, your previously visited pages will take longer to reload if you delete all the files in the browser cache. Cache deletion may be a good practice for privacy oriented users, or for people transitioning to a different browser, but we would not wipe the cache by default. Problematic analysis results In our tests, CCleaner detected a whopping 7. GB of log files created by Windows, which it automatically flagged for deletion. Many of these were hundreds of megabytes in size. However, log files can be useful if your computer is misbehaving, as they contain error messages to assist you or a technician. Theyre not supposed to get anywhere near this large, and old logs just tend to sit unused and take up space, but wed prefer to keep at least the most recent one by default, in case something goes haywire later. Meanwhile, Windows own Disk Cleanup tool detected 7. MB of deletable system files that CCleaner did not find. These were previously installed Windows Update patches. If Windows says that theyre OK to delete, its a mystery why CCleaner which ordinarily takes a more aggressive approach did not flag them. While 7. 50. MB isnt a huge amount of space, the Disk Cleanup report made us wonder what else CCleaner might be overlooking or not prioritizing. Lastly, CCleaners own Windows Registry Cleaner tool flagged CCleaner itself for having an Obsolete software key. We had not installed CCleaner or any other Piriform product on this copy of Windows before, so the offending file wasnt left over from a previous version of CCleaner. Its not clear what would happen to CCleaner if we told it to delete its own Registry entry, but users not closely inspecting the Windows Registry Cleaner results might find out the hard way. Bottom Line CCleaner remains a handy tool for freeing up storage space, letting you customize how it works and permanently erase files. However, some behavioral quirks indicate that its not quite a full replacement for Windows built in disk cleanup tools, which tend to be more conservative but also safer. Greater Phoenix Real Estate.
